Sound sources localization algorithm in shallow sea based on VTRM

This paper deals with the problem of the sound sources near-field localization in shallow water. It is important to develop algorithm for solving the problem of the non-point sources localization in the multi-path channel. The key work of this paper is to introduce a phase conjugation virtual time reversal mirror (VTRM) anti-multipath algorithm used in focused beamforming. Because of making full use of the spatial geometric relationship between scanning planar and receiving array in the near-field, the algorithm can estimate the channel impulse response function without any information about the channel and receiving signals, and can match the practical channel effectively.
