摘要
分析了声纳宽带接收机在频分法抗同频干扰的性能,指出了宽带接收机即使采用频分抗干扰措施仍存在很强的压制干扰。为了抑制这种干扰,提出一种窄带接收机结构。从理论上分析了该结构的性能,并用湖试对该方法进行了检验,试验结果表明它具有很好的抗同频干扰能力。
In this paper,the capability of wideband receiver to suppress in-line jamming is analyzed.It is pointed out that wideband receiver still has strong oppressing jamming even if frequency division method is used.A kind of narrowband receiver is presented in order to improve the capability of wideband receiver.The capability of the narrowband receiver is analyzed and verified by the experiment in lake.The experiment results show that its capacity to suppress in-line jamming for active sonar is good.
