摘要

针对使用矢量标量接收器对宽带水声信号进行全息处理，提出了一种新的自适应方法。当传播环境的传递函数信息不存在时，该方法可通过噪声场检测水下声源并对其进行定位。与早先提出的自适应算法相比，该方法实施起来更简单，抗干扰能力更强。本文介绍了数值实验中获得的结果，这些结果表明，在存在导致噪声源声场模式相互作用的密集内波的情况下，该方法具有稳定性。

Adaptive Method for Holographic Processing of Broadband Hydroacoustic Signals

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.
