为了满足在线导鱼雷发射前预知攻击弹道的需求，提出一种基于推算方位的线导鱼雷方位导引预估弹道计算方法。首先介绍线导鱼雷方位导引方法；然后在使用目标运动要素推算目标方位序列基础上，采用新构建的预估弹道计算模型，计算线导鱼雷方位导引预估弹道；最后采用典型攻击态势进行了仿真验证，并分析推算方位使用的目标要素误差对预估弹道准确性的影响。结果表明，针对匀速直航目标在推算方位使用的目标运动要素输入误差较小情况下，使用该方法预估的线导鱼雷方位导引弹道与期望弹道一致概率较高，可以满足在线导鱼雷发射前预知攻击弹道的需求。
In order to meet the demand of predicting the attack trajectory of wire-guided torpedo before launching,this paper proposes a method for predicting wire-guided torpedo trajectory based on calculating the target’s bearing.Firstly,the azimuth guidance method of wire-guided torpedo is introduced;Then,on the basis of calculating target azimuth sequence by using target motion elements,a new predictive trajectory calculate model is adopted to calculate the predictive trajectory of wire-guided torpedo;Finally, to validate our model, we conduct simulations utilizing common attack scenarios, accompanied by an examination of how error in the target parameters affect bearing estimation and trajectory prediction.The results show that the azimuth-guided trajectory of wire-guided torpedo estimated by this method has a high probability of being consistent with the expected trajectory when the input error of the target motion elements used in the calculation of bearing is small,which can meet the demand of predicting the attack trajectory of wire-guided torpedo before launching.
