, Description:TECHNICAL FIELD
[0001] The present disclosure relates, in general, to weapon system, and more specifically, relates to a means for identifying the object falling position using strength-based centroiding.

BACKGROUND
[0002] In a defence situation, it is necessary for a weapon crew to be able to assess the accuracy with which rounds fired by their weapon are hitting intended targets. Artillery has been called the king of battle because it brings to the field to the battle greater power than the infantry. Throughout modern history, armies have relied on artillery firepower to defeat the enemy. The long-range artillery weapons artillery had been primarily a direct fire weapon, however, the limitation of the direct fire weapon is the line of sight.
[0003] Indirect fire is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire. The main aspect of indirect fire is to increase the casualties to troops, inhibit mobility, suppress or neutralize weapon systems, damage equipment and installations, and demoralize the enemy. The indirect fire aiming is performed by calculating the azimuth and inclination of the barrel with respect to the target and may include correcting the aim by observing the fall of the shot and calculating new angle.
[0004] Few existing mechanisms in the field of indirect fire weapon may include an indirect fire weapon aiming device with an angular displacement sensor and an azimuth communicator, where the azimuth communicator communicate the launcher azimuth to the angular displacement sensor so that the angular displacement sensor can measure the angular displacement of the launcher relative to a reference bearing and provide the angular displacement output. Another existing exemplary mechanism may include an optical aiming device for indirect artillery fire, where the optical aiming device permits a relatively great displacement of the weapon due to recoil or other reason without the necessity of repositioning the aiming device. However, these existing mechanisms suffer from the limitations of inaccurate estimations of the parameters that may affect the accuracy and final impact point of a projectile.
[0005] Therefore, there is a need in the art to provide a means that determine the falling object position by using the strength-based centroiding of particle dispersed by the blast while monitoring the intended tracked target strength.

The radar 102 configured to generate radar data (also interchangeably referred to as a set of data) representing the actual trajectory of one or more objects with respect to the target. In an exemplary embodiment, one or more objects may include a shell, bullet and a combination thereof. To determine the shell falling position, this method is updated in the centroider application for the radar system. The centroider concept can be updated with this method and deploy on any hardware or target system.
[0035] The radar technology applied to the existing science to improve the adjustment of the indirect firing. The target tracked by radar 102 and converts the target coordinate with respect to the gun and passes the information for the next firing. The indirect fire aiming is performed by calculating the azimuth and inclination of the barrel with respect to the target and may include correcting aim by observing the fall of the shot and calculating a new angle. Information on object particles (also interchangeably referred to as one or more objects) is maintained by scheduling the beam in the intended position. Object particles, which are within the radar coverage get detected. Strength information for each particle is considered and compute the centre point of the object falling position. The proper computation of object falling point has the potential for future object engagement. Discrimination of strength of target and object particles based on historical information of the intended tracked target.
[0036] In an exemplary embodiment, object falling position may be identified by calculating the centroiding of particles using individual particle’s strength and position. Position identification of object falling position can be based on centroiding of object particles after the burst. To perform centroiding, each particle’s strength may be considered.
