Abstract
In order to improve the performance of sound pressure vertical array,optimize the hydrophone array structure,the time-reversal passive location technology with vector vertical array is researched and three methods are given in this paper. We compared the vector vertical array and the sound pressure vertical array in processing gain of TRM through computer sim-ulation, and analyzed the relationship between positioning performance and parameters such as SNR, number of array ele-ments and spacing between elements. The simulation results show that, when the detection probability is 0.8, the detection threshold of vector vertical array is 1dB-3 dB better than that of sound pressure vertical array. For the wideband signal of 2kHz-4kHz,the vector vertical array can obtain better time-reversal passive location effect by using four elements array with 2 meters element equal spacing.关键词
