摘　　要：水压引信有非常优越的抗扫性能,但在高海况下水压引信抗自然干扰能力差,导致虚警率增高,动作概率下降。针对如何能在高海况的强干扰下降低水压引信的误动率,并且能够在低信噪比下准确检测出舰船目标的技术难题,提出对水压信号采用频域处理的简化算法来解决这一问题。Hydrodynamic fuze has very superior anti-sweeping performance,but it is hard to resist natural disturbances at abominable sea state,which leads to the increasing of false alarm rate and decreasing of action probability.Considering the issue of how to reduce the ratio of mistake action under strong disturbances at abominable sea state and accurately detect the ship target in low signal-to-noise ratio,this paper presents to use the simplified algorithm of frequency domain processing to solve the issue.
