摘　　要：在研究潜射鱼雷导引方式的基础上,建立了潜射声自导鱼雷、潜射线导鱼雷的攻击弹道模型,给出了利用来袭鱼雷报警舷角变化规律判别攻击弹道类型的方法,并对不同对抗态势下的鱼雷舷角变化率进行了仿真分析。结果表明:当鱼雷非大舷角或小舷角来袭时,现在方位法弹道的鱼雷相对舰艇的舷角变化率明显大于提前角弹道的鱼雷,鱼雷的舷角变化信息作为中远距离来袭鱼雷类型识别的重要依据。Based on guiding method of torpedo launched by submarine,the attack trajectory models of acoustic homing torpedo and wire-guided torpedo were established.The judging method of attack trajectory type of incoming torpedo using bearing information was presented,and the rates of bearing change of different trajectory torpedo to ship were calculated and analyzed at different tactical situations.The results indicate that the bearing change rate of torpedo in current azimuth trajectory is significantly greater than in optimal lead angle trajectory when the torpedo coming from not big bow bearing or small bow bearing.The rate of bearing change of torpedo to ship is as an important basis for type recognition of torpedo coming from intermediate and long distance.
