    New Delhi: A state-of-the-art target training system, DHVANI (Detection and Hit Visualization using Acoustic N-wave Identification) developed by CSIR-National Aerospace Laboratories (CSIR-NAL), Bengaluru, for perfecting marksmanship skills by accurately determining the location of bullet impact and providing real-time feedback, has been validated and approved for induction into the Indian Army. After rigorous field trials at Army ranges in Bengaluru, Secunderabad, and Infantry School Mhow, DHVANI will now be formally handed over to the Indian Army in Secunderabad tomorrow (on 03 July 2014).

    The marksmanship training requires positive and negative reinforcement of shooting techniques immediately after each shot is fired. However, the manual system currently used by the Indian Army involves the marksman firing shots at the target and subsequently walking up to the target (about 300 m) and identifying whether the shots were a hit or a miss. This primitive type of marksmanship training exhibits not only high turnaround times but is also inconsistent, unreliable, inaccurate and subjective. Furthermore, the marksmanship training systems available from advanced countries for sale are mostly based on old technology of 1980s, which also have exorbitant cost of ownership as they are not customized for the Indian environment and necessitate expensive after-sales service due to the black-box approach of the manufacturers.

    This modern indigenous marksmanship training system, DHVANI is tailor made by CSIR-NAL to meet the requirements of the Indian Army at a cost lower by 40 per cent of the cost of similar systems available elsewhere in the world without compromising on the performance – the whole process i.e. firing a shot to displaying of results at the shooter end takes less than half a millisecond. At the shooter end, a multi-functional interactive GUI on aMIL grade laptop displays the results. Furthermore, a comprehensive database containing personnel details, shots fired and performance statistics ensures comprehensive logging for later analysis. The system originally developed for use by the Indian Army has potential application for use by the paramilitary forces and also in the sports sector.

    The entire development process beginning from the Indian Army’s request to the development of the prototype testing took only 10 months. Each prototype currently costs Rs. 9 lakh/firer lane, which is significantly lower than the price tag of Rs. 15-18 lakh for each firer lane of older generation wired systems in use with the Indian Army.

    The system is based on the basic principles of gas dynamics and aero-acoustics. Essentially, a bullet is a supersonic projectile, which generates a shock wave from its leading edge, continuously at every point of its supersonic travel. At any instant along the bullet path, the shock wave envelope propagates in an invisible-cone continuously outward at an angle related to its Mach number. The pressure wave in air caused due to the passing of the bullet results in a pressure profile known as‘N-wave’ because of its shape.

    The hit location of the bullet is then determined accurately by using an array of sensors to record the acoustic pressure rise due to the passing shock from the bullet. Using advanced algorithms developed at CSIR-NAL, the recorded signal from the sensors are analyzed for detection of N-wave, and the geometrical shape of the shock wave is then used to determine the coordinates of the bullet on the target. These coordinates are then wirelessly transmitted to a display at the shooter end. The entire process starting from firing a shot to the display of results at the shooter end takes less than half a millisecond.

    Nope. This is a training aid to help soldiers at the rifle range know where their shots are landing. Such systems are already in place in most Regimental training centres but the tech is of foreign origin.

    Can you provide a summary of what this video says please?

    The video says about the system of "Dwani"(Voice) is used for getting the result of bullets are fired, the foreign systems are old and costlier as well as not made for weather of India, the foreign systems are costlier and also the maintenance cost is also high, Hence NAL laboratory invented this Dwani system which give result regarding bullets fired. on bases of Acostic Technology.

    The cost of this system is only 9 lakhs whereas the foreign instruments were 15 lakhs plus. Before this technology when the soldiars fire bullets, after that to get the result they went to the target and read how many bullets on which ring hit, after fire soldiars went to their targets which are sometime at 500 meter distance which is very time consuming and lenghthy process, then after the other technic used was there were tunnel near the target, after firing is over they were called by phone and they get up and read the target, But now the present system is Computerrised and just in miliseconds give the details about firing, which will given to the militery, then paramilitery and then shooting places (where shooting sport, games are going on).

    So in short the System is for Cost Effective, Indeginious, Latest and powerful, As per indian environment and condition, Perfect, for Identify whether targets hit properly or not and analysis. And if UK want it they have to give $ or euros or pounds to India :)
    well i think it was like Boomregs of US that identify from which direction bullet is fired. :(
