摘要
高海况下识别水面目标是鱼雷主动声引信的一个技术难题。该文利用仿真波浪，分析了波浪和典型目标的两个特征量——突变量与变化累积量，给出了波浪特征量的统计检验结果和典型目标特征量的解析表示，分析了影响目标特征量的主要因素，给出了目标特征量随攻击舷角、相对速度等的变化曲线，得到识别水面目标的最小吃水灵敏度，最后介绍了基于特征参量法的鱼雷主动声引信数字化处理系统实现方案。
It is a problem for the active acoustic fuze for a torpedo to recognize a surface ship in a high state of the sea.Based on simulated waves,this paper analyzes the two characteristics JUMP and DIFFERENCE of a wave and typical ship and provides the statistic results of the wave characteristics and the analytic results of the typical ship and analyzes the main factors that affect the ship characteristics and gives the curves of ship characteristics varying as an attacking angle and relative velocity,thus obtaining the recognizable minimum draft of the surface ship.Finally,the paper introduces the realization scheme of the digital processing system of the active acoustic fuze for the torpedo based on the above characteristics.
