A NEW METHOD FOR UNDERWATER BALLISTIC MEASUREMENT BASED ON NEMS VECTOR HYDROPHONE
In this paper, the author applied two-dimensional NEMS vector hydrophone to the research of underwater weapon ballistic measurement, and designed underwater ballistic measurement system based on vector hydrophone. Under the conditions of small size and low frequency, precise direction measurement and distance finding of underwater moving target can be realized. Interferences of SNR (signal-to-noiseratio) and varied algorithms to the measurement precision have been researched, and the performance of system has been analyzed by measured radiated noise of warship. The results of simulation and test show that this measuring system has good advantages of small size and high precision. This research tries to provide an effective technical approach for ballistic measurement of underwater weapon.
