摘　　要：为模拟水下目标在被追踪过程中的声反射信号,根据鱼雷和目标的运动方程,采用尾追法进行弹道分析,研究鱼雷追踪目标的轨迹,同时根据鱼雷与目标的距离,生成不同自导信号形式,并通过计算得到反射信号的多普勒频偏和信号强度,最终将数字信号转换为模拟信号供实验室测试,或为其他任务提供模拟信号,对水下目标的设计及研制具有重要作用。To simulate the reflected sound signal of the tracked underwater target, according to the equations of motion torpedoes and targets, the tail chase method is used to analyze the trajectory of torpedo tracking the target. The different self-guided signals are generated according to the distance between target and torpedo, and then the reflected signal＇s Doppler frequency deviation and strength are obtained by calculation. The digital signal is converted to an analog signal for laboratory testing, or for other tasks. It has an important role in the design and development of underwater targets.
