3 Background of the Invention
Digital radio frequency proximity detector is a type of radar system used in
aerospace and aviation applications to determine the range and velocity of
an aircraft, helicopter. spacecraft, static or dynamic targets. It works by
digital radio frequency memories based by considering radio frequency
echo's signal from different targets or sources of sensors to calculate the
target range and its velocity. Digital radio frequency proximity detector
refer figure 1 is the mission critical which comprises of two Radio
Frequency trans-receivers (RFTR), Frequency synthesizer and Power
divider (FSPD), Automatic link establishment module (ALEM) and DC
power supply module (DPSM).
The present functionality for Digital radio frequency proximity detector is
operable without encrypted message signal; during mission critical
automatic link establishment module processing unauthenticated messaée
signals received in the same frequency band from foe. Since the
transmitted message signal is not encrypted, foe can retrieve the
information then generate false messages to misguide, further enemy can
introduce electronic counter measures to spoil the critical mission. The
entire operation is tested functionally in the target simulator tester. During
go and no—go functional checks of the automatic link establishment module is tested with target simulator and verified the functionality of the module
for transceiver message signals up to two channels. The same signals
communicated and processed with data acquisition card routed through
onboard sensors. During 90 and no—go functional checks obseNed the
snag related to communication delay due to progression of
unauthenticated message information generated by enemy and
subsequently, mission acquisition problem found due to electronic counter
measures introduced by foe. Also observed the automatic link
establishment module hanging due to in excess of throughput and got
error in communication interfacing with onboard processor. The failure of
critical mission operation by foe due to electronic counter measures
introduced by decode unencrypted transmitted message generated from
the automatic link establishment module during exercise in digital radio
frequency proximity detector system.
The proposed high crack resistive encrypted message with quantum
encryption in automatic link establishment module can provide secured
message transmission, which results in inclusion of unauthorized false

forced due to secure message signal transmission. Further, it avoids the
critical mission failure during operation by realize quantum encrypted
message signal from the automatic Iink establishment module in digital
radio frequency proximity detector system.

enemy in the same frequency of message transmission. Hence, It is obvious the foe decodes unsecured message signal transmitted without
encryption which results in initiate false messages in the same band of
‘frequency to encounter the mission.

Automatic link establishment module designed with quantum encryption
functional block based on quantum encryption phenomenon, which taps
the uncertainty of the quantum world. With it's create a message
communications channel where it is impossible to eavesdrop without
disturbing the transmission, even if the eavesdropper has unlimited
computing power. The quantum technique has a fundamental uncertainty
and there's no way to avoid it. That uncertainty can be used to generate an encrypted message. As they travel. photons vibrate in some direction;
up and down, left to right or more likely at some angle. When a large
group of photons vibrate in the same direction they are polarized.
Polarized filters allow only photons that are polarized in a certain direction
through the rest are blocked.
A horizontal polarization filter only allows horizontally polarized photons
through. Turn that filter 90 degrees, and only vertically polarized photons
can come through. A pulse of horizontally polarized photons pass through
a horizontally polarized filter, they all get through. Slowly turn that filter 90
degree; the number of photons getting through gets smaller and smaller.
until none get through, since the photons are horizontally polarized. But in
quantum technique. each particle has a probability of suddenly switching
its polarization to match the filter. The angle is a little bit off, it has a high
probability, the angle 90 degree off, it has zero probability and the angle is 45 degrees off. it has a 50 percent probability of passing through the filter.
Uncertainty property of photon realizes binary sequence of digital bits to
form quantum encrypted information. The same concept implemented in
automatic link establishment module.
The design of the automatic link establishment module with quantum
encryption process provides Inputs and outputs permits adequate
interfacing to advanced control and status fetching capable field
programmable gate arrays and flash memories toward the needs of
communication and radar systems. It has two simultaneously accessible
ports for instruction/status and data. The data port is reconfigurable to
transfer data in bit, byte formats. And all Inputs or Outputs operations are
fully supported by interrupts and a direct memory access interface.
The layout was generated in a hierarchical fashion using a combination of
optical quantization and digital radio frequency memories with configurable
logic blocks. ln-hoUse simulated annealing and routing system was used to route lower level blocks while the upper level blocks were routed by
hand to minimize die area. To ensure correctness, the layout was
extracted in a hierarchical fashion and compared at all levels to
schematics which were logically simulated at the gate level. The design
methodology permitted design rule checks and electrical rule checks to be
performed hierarchically.
A working model of quantum encryption message for secure
communication is realized in automatic link establishment module. The
details of various designed sections of ALEM are as follows.
DC Input Power Supply & Signal distribution through 25pin micro D type
connector vital to provide supply to the automatic link establishment
module required supply +5V, maximum current consumption of 1A‘
SMA | & Q-signals to ALE Module provides input signal from the down
converter module with the level of maximum 1.8V.
Transformers for l-Q Signals are wide band transformers with maximum
voltage rating of 500 Vrms and 250 mA max current rating. It has
capability of inter winding isolation and it can handle 114 Watt RF input
power. Operating temperature of transformer is —40°C to +85°C.
Transformer primary and secondary impedance ration is 1:1 band width
0.050 to 200MHz, insertion loss 0.20 dB max.
High rate Giga samples per second Analog to Digital Converters are high
performance and low power consumption analog to digital converter with
maximum sample rate of 3 GSPS bit resolution with no missing codes. An
internal high bandwidth sample and hold and a low jitter clock buffer help
to achieve high data rate of random sequence of message bits due to of
input signal link quality uncertainty levels compensation ADC capable of
feature to operate coarse and fine gain options to improve link quality
performance at lower full-scale analog input ranges. The sequence of bits conversion process is initiated by the rising edge of the external input
clock. Once the signal is captured by the input sample and hold, the input
sample is sequentially converted by a series of lower resolution stages,
with the outputs combined in a digital correction logic block 14-bis of
output available. It supports Inputs signal with amplitude of 400mVpp.
Input voltage required to operate is 3.3V DC and output can obtained 1.8V
to 3.3V digital Supply‘
Crystal oscillator act as self-generator, its output frequency is from 1.5MHz
to 125MHz. Reliable frequency stability obtained based on working
temperature range from -40°C to +85°C. Required power supply voltage is
+ 5.0 V + 10% Vdc. (a) Maximum Suppiy Current 20mA max for oscillator

to 49.99MHz output and (c) Max. Supply current draws 50mA max. for 50
to 125MHz output. Crystal oscillator provides source to the various clock buffer section to distribute clock frequency to the internal functional blocks.
It has three control terminals and it allow up to 33 = 27 combinations.
Additionally, an enable terminal is provided to disable or enable all outpuls
simultaneously.
Surface mount transzorb provides circuit protection by transient surge
voltage suppression. It has excellent clamping capability and very fast
response time, operates with Low incrementa! surge resistance. Transzorb
used to protection ALEM against voltage transients induced by inductive
load switching and lighting on ICs, semiconductor devices. signal lines of
sensor unit.
The switch power module is a complete, easy-to use DC-DC solution
capable of driving up to a 3A/4A load with exceptional power conversion efficiency, output voltage accuracy, line and load regulation. It has
enhanced thermal performance and allows for manual or machine
population. It accepts an input voltage rail between 2.95 V and 5.5 V and delivers an adjustable and highly accurate output voltage as low as 0.8 V.
One megahertz fixed-frequency pulse width modulated switching provides
a predictable EMI characteristic. Two external compensation components
can be adjusted to set the fastest response time with use of ceramic or
electrolytic output capacitors. Externally programmable sofl-stan capacitor
facilitates controlled start up. The power module is a reliable and robust
with the following features: lossless cycle-by—cycle peak current limit to
protect for over current or shod-circuit fault, thermal shutdown, input under
voltage lockout, and pre-biased start-up. The switch power module is a
step—down DCvto-DC power module. It is typically used to convert a higher
DC voltage to a lower DC voltage with a maximum output current of
3 AMA to cater all the functional blocks of automatic link establishment
module.
The power supply sequencer offers the easiest method to control power
up sequencing and power down sequencing of multiple Independent
voltage rails. By staggering the start-up sequence, it is possible to avoid
latch conditions or large in-rush currents that can affect the reliability of the
system. The simple sequencer contains a precision enable pin and three
open-drain output flags. The open-drain output flags permit that they can
be pulled up to distinct voltage supplies separate from the sequencer Vdd,
so as to interface with l requiring a range of different enable signals.
When the power sequencer is enabled, the three output flags sequentially
release, after individual time delays, thus permitting the connected power
supplies to start up. The output flags follow a reverse sequence during
power down to avoid latch conditions. To operate requiring a flag output
voltage that is different from the Vcc, a separate Flag supply used to pull up the open-drain outputs of the simple power supply sequencer. This is
useful when interfacing the flag outputs with inputs that require a different
voltage than Vcc. The flag supply voltage and enable voltages are isolated
from Vcc + 0.3 V supply. During power up sequencing, it maintains the enable voltage to a level below the EN voltage threshold until Vcc rises
above the minimum operating voltage. Enable is connected to Vcc,
undefined operation at the flag dutputs occur, especially during slow Vcc
rising slew rates. For systems requiring only power up sequencing, a
capacitor at the enable pin used to create a delay or a resistor divider
used to enable the device based on a certain voltage threshold. While
these solutions work for power up sequencing, it does not power down the
flag outputs in sequential fashion because the flag outputs follow the input
supply. For ALEM requiring both power up and power down sequencing,
use an external enable signal. such as a GPIO signal from a
programmable logic controller, to properly control power up and power
down of the flag outputs.
The voltage regulator provides extremely low-dropout, low-power linear
voltage regulator features high power-supply rejection ratio, ultralow noise,
fast start-up, and excellent line and load transient responses in small
outline. it is six pin surface mount voltage regulator. Stabled voltage
obtained with a small 1pF ceramic capacitor on the output, Device
achieves fast start-up times approximately 50 us with a 0.001-uF bypass
capacitor and consumes very low quiescent current of 265 uA. Moreover,
when the device is placed in standby mode, the supply current is reduced
to less than 1 pA. Voltage regulator exhibits approximately 33uVrms of
output voltage noise at 3V with a 0.1pF bypass capacitor. The voltage
regulator combines the high performance required of RF and precision
analog applications with low current consumption in ALEM. It’s operating
temperature range from -40°C to +125°C.
Light emitting diodes provided to find out status of power up condition of
ALEM and operational functional block through Built In Test Equipment by
visualization.
The Level translator used for voltage level-shifting for interfacing devices
and addressing mixed voltage incompatibility. It is ideal for data
transmission where direction is different for each channel. Voltage level
translator operates from 1.65 V to 55 V and 1.65 V to 5.5 V. The signal
translation between 1.65 V and 5.5 V requires direction control and output
enable control. In a bidirectional application, the enable times provide the
maximum delay from the time the DIR bit is switched until an output is
expected and three level translators designed to cater all in and out
signals from peripherals to the FPGA in ALEM.

communication application. It has an extended ambient temperature rating

to 256 nodes on a bus and capable of signalling rates up to 1 Mbps with
thermal shutdown protection. It operates from 3.3V to 5Vsupply inputs and
provides communication with internal on board processor.

input/output serial Flash memory device. It features a high-speed SPI—
compatible bus interface, execute-in-place functionality, advanced write
protection mechanisms, and extended address access. Innovative, high
