浅海中单矢量水听器高分辨方位估计方法
Research on high-resolution DOA based on single vector hydrophone in shallow water
摘要
Abstract
In order to increase the performance of the high-resolution DOA estimation for the single vector hydro-phone in shallow seas, the impact caused by the channel on sound propagation is fully considered. By combining the ocean sound propagation physical model and the robust adaptive beamforming method, the vector optimization algorithm based on the single vector hydrophone and normal mode theory is proposed according to the array manifold characteristics of the single vector hydrophone then the high-resolution DOA estimation of the single vector hydro-phone is realized. Simulation results show that the algorithm may realize the DOA estimation of narrowband and wideband signals only by utilizing a single vector hydrophone, in addition, when the SNR ( signal-to-noise ratio) is high enough, the estimation without bias may be realized. The results of the sea trial data processing verify the ac-curacy and effectiveness of the algorithm.关键词
