摘　　要：已知的高速运动相干声源会对矢量水听器的方位估计造成干扰,瞬时相关积分可修正线谱信号的频带展宽,但无法修正多普勒频移,不能通过固定参数滤波器抑制其干扰。将矢量水听器组合振速做为参考输入的自适应抵消器可抑制相干声源干扰,通过仿真验证此方法有效可行。It is known that high-speed interference noise source can suppress DOA estimated by the vector- hydrophone, while the instantaneous correlation integral is able to correct widening frequency of linear spectrum, but it can＇t correct Doppler shi~, and the interference suppressing is failed to be cancelled by setded parameter filter. The interference suppressing can be counteracted by the adaptive cancelling filter with reference input collected from the combined velocity of vector-hydrophone, and the simulation results indicates that the method is viable and effectual.
