Abstract:
In order to solve the problem of multipath propagation of sound waves generated by sea surface reflection, a time difference of arrival (TDOA) localization method based on maximum or minimum value screening is proposed. Firstly, based on the propagation characteristics of underwater acoustic channel, the distance equation of propagation path in the case of sea surface reflection and linear propagation is derived, and four kinds of measurement value equations of TDOA localization in the deepsea multipath environment are established. Then, the measured TDOA values of linear propagation of sound waves are obtained by screening the measured TDOA values for the twice maximum or minimum value. Finally, the underwater target localization is realized based on Chan and Taylor algorithm. Simulation results show that the localization accuracy of this algorithm is within 1 meter in the deep sea multipath environment with the ocean depth of less than 100 meters, which is greatly improved compared with the multipath TDOA algorithm based on statistical characteristics. The proposed algorithm can effectively eliminate the multipath error in the deep-sea environment and has high practicability and reliability.
