Adaptive Method for Holographic Processing of Broadband Hydroacoustic Signals
摘要
Abstract
A new adaptive method is proposed for holographic processing of broadband hydroacoustic signals using vector-scalar receivers. The method allows underwater sources to be detected and localized by their noise field when information on the transfer function of the propagation environment is unavailable. It is simpler in implementation and more disturbance immune compared to earlier proposed adaptive algorithms. The results are presented that have been obtained in the numerical experiment on the stability of the method in the presence of intensive internal waves causing interaction of sound field modes of the noise source.
