CSIR-NAL has enhanced its Detection and Hit Visualization using the Acoustic N-wave Identification (DHVANI) bullet impact tracking system.

Development of DHVANI commenced in 2014 and has evolved to take the form of a single unit rather than a modular configuration.

At present the system is used to train sniper and other rifles. Sources have revealed that the Indian Air Force has procured 12 of these systems through a global tender for the Southern Air Command. A further two are in service at the Indian Army's Artillery Base 515 Workshop, Bangalore.

DHVANI was specifically designed for the Indian armed forces, which began testing the system in 2014 at army ranges in Bangalore, Secunderabad, and the infantry school in Mhow.

The automated system detects the pressure waves generated by a bow shock wave formed ahead of a blunt supersonic body, in this case a bullet.

Sources have indicated that the improvements to the system have come in the form of reductions in the size of the motor and the electronics used, as well as the use of carbon composites that help to reduce weight; the system has also been made more durable, enabling it to withstand impact loading.

The system can pop up and down, swivel and slice, and the sensors need an overall ground area of 0.5 m x 0.5 m.

It is also understood that the system can be modified for use in training for land, air and naval platforms, including tanks, fighter aircraft, and ship-based gunnery, provided the projectiles are supersonic.

Sources also clarified that the initial deliveries were from a limited series production by CSIR-NAL for the army. CSIR-NAL continues production, however, for the Indian Army, as transfer of technology has led to licence production for its needs.
