摘要
基于脉冲回声探测的主动声引信识别水面舰船，随机起伏的波浪回声干扰是限制其可识别水面舰船最小吃水的主要因素。对此本文提出了抗波浪回声干扰的自适应预测法，通过预测某一时刻以后若干波浪回波脉冲的到达时间，并与实际回波时间相比较，从而确定是否存在水面舰船。文中给出了该法的方案原理、算法及实验结果。
For the active acoustic fuze for a torpedo on the basis of the distance measurement done by using acoustic pulses, the echo of a randomly undulating wave is a main disturbance to recognize a surface ship. This paper puts forward an adaptive prediction method to reduce wave disturbance. With the method, the arriving time of next echo can be predicted by using past time data and real arriving time is compared with the predicted one so as to determine whether a surface ship exists. This paper provides the principle, algorithm and simulation results of this method.
