Technology development, to detect the bullet location in the target plane for the subsonic weapons, which has bullet/ammunition velocity less than 450 m/sec at the target

Acoustic sensor based solutions are available to detect the bullet locations, for the supersonic weapons, which has bullet/ammunition velocity 450 m/sec or more at the target. Acoustic sensors are unable to detect the shock waves generated by bullets of subsonic weapons due to low signal strength, as bullet velocity of such ammunition is less than 450 m/sec at the target.

Required technology needs to be developed to resolve the above challenge, with following key specifications:

• Accuracy: 5mm or less within a radius of 8 cm (from target centre) and up to 10 mm anywhere on the target at wind speed less than 1.5 m/sec.
• Detection Zone: 80 cm left and right from the target centre and 180 cm from the target bottom.
• Max Rate of Fire: 18 rounds/second.
• Suitable for stationary target, pop-up target, turning or rotation target, as well as for moving target exercises.

Future Expectation from the prototype / Technology developed

1. The technology developed shall be integrated with Location Of Miss And Hit System (LOMAH) system, to automate the existing training methodology of weapons training at the existing firing ranges. 
2. It is aimed to reduce the training duration by training more firers in a specified period of time, manpower requirement for the conduct of firing and provide immediate feedback of the hit as well as miss bullets.
