对来袭鱼雷的制导类型进行识别是水面舰艇实施有针对性鱼雷防御的前提条件，方位变化率则可作为类型识别的一个重要的依据。首先，从不同类型潜射鱼雷的发射方式和弹道特征入手，分别推导出潜射直航鱼雷、声自导鱼雷、尾流自导鱼雷方位变化率的表达式。其次，仿真分析了不同类型潜射鱼雷方位变化率的影响因素。最后，在给定的态势下，给出了四种不同类型潜射鱼雷方位变化率随雷舰距离的变化规律曲线。仿真结果能为鱼雷制导类型识别提供一定的参考依据。

The guidance type identification of an incoming torpe do is a premise for surface ships to defend against torpedoes pertinently. And the bearing rate can be an important basis for identifying the guidance type. Firstly, according to the launch-ing modes and trajectory characteristics of different types of torpedoes, the expressions of bearing rate for straight-running tor-pedo, acoustic homing torpedo and wake homing torpedo are deduced. Secondly, the factors influencing bearing rates of dif-ferent types of torpedoes are analyzed through simulation. Finally, in a given situation, the curves that the bearing rate chan-ges along with the distance between torpedo and surface ship are provided. The simulation results can provide a reference for torpedo guidance type identification.
