摘要：
Aiming at the typical environment of underwater target passive positioning, the performance of a two-dimensional DOA estimation method based on L-shaped array is simulated. Firstly, the far-field underwater acoustic data received model of L-shaped sonar array is given; Secondly, combined with the MUSIC beamforming technology, the basic principle of two-dimensional DOA estimation of L-shaped array is studied; Finally, combined with the typical underwater acoustic detection environment, computer simulation experiments are carried out, focusing on the influence of SNR, the number of array elements, target azimuth interval and other parameters on the performance of the algorithm.
