DESC:TECHNICAL FIELD
[0001] The present invention relates generally to jamming systems. The present invention, more particularly, relates to a jamming system for jamming one or more electronic devices.
BACKGROUND
[0002] Typically, communication / Radio Controlled Improvised Explosive Device (RCIED) threats have become most common threats in today’s world. The most common source of these threats comes from the electronic devices, for example cellular/ mobile phones. The mobile phones are used to control the RCIED bombs or explosive devices that can be detonated by remotely controlling the mobile phones. To counter these threats from the mobile phones, a jamming system is required. However, network operators use sophisticated technologies (such as frequency hopping, Spread Spectrum, and Orthogonal frequency-division multiplexing (OFDM)) in order to counter the mobile jammers. For example, an existing Barrage Jamming technology used in mobile jammers do not provide the sufficient jamming range for current mobile phone technologies as the power per Hertz (Hz) is less in case of Barrage Jamming.

[0003] US7982654 B2 discloses a smart signal jammer capable of jamming pulsed signals that receives a description of an unwanted signal or signals to be jammed, and transmits one or more jamming signals in one or more temporal transmission patterns of pulses that jam the unwanted signal or signals. The jamming signal power is spread across the frequency ranges, which indicate that the jamming is also done for unwanted spectrum, lowering the jamming ranges.

[0004] A new jamming technology is required where only the control channel of the mobile operator is jammed in order to increase the power per Hz.

[0005] Therefore, there is a felt need of an invention which solves the above defined problems and provides a jamming system for jamming one or more electronic devices.

[0036] Figure 2 illustrates a block diagram (200) depicting a jamming system (104), according to an exemplary implementation of the present invention.

[0037] The jamming system (hereinafter referred to as “system”) (104) includes a search receiver (202), a controller (204), an exciter (206), an amplifier (208), a receiving antenna (210), and a transmitting antenna (212).

[0038] The receiving antenna (210) is configured to receive signals of cellular phones. In an embodiment, the receiving antenna (210) is an Ultra-Wideband (UWB) receiving antenna (210), which uses for a low energy level for short-range, high-bandwidth transmission over a large portion of an operator frequencies network.
