Usbl Array Of Applied Research On The Mine Target Detection And Location

The application of the ultra-short baseline theory to detect and localization of the mine is mainly researched in this dissertation.Based on the basic theory of the passive and the shape character of the mine, The four cell square lineup is choosed to be researched. Firstly , The basic theory of the ultra-short baseline system is dissertated. And then, several typical localization model of four cell lineup is analyzed and investigated thoroughly. A optimal localization model is educed by contrasting performance and analyzing precision.The generalized correlation method is choosed as the method of time delay estimation in this dissertation. And a optimal arithmetic is educed by analyzing and contrasting many arithmetics at present.At last but not the least, the software and the hardware of the passive acoustic localization DSP system is dissertated emphatically, including the choice of chip, design of the circuit debugging of the hardware, design of the software and the realization of arithmetic. And validate the correctness of the software and the hardware.
