一种基于灰关联的目标运动要素解算方法

针对线导鱼雷远距快攻的特点，探讨了一种纯方位条件下基于灰关联的快速获取目标运动要素的方法：将目标初距和速度进行合理划分，根据实测目标方位变化量计算舷角值，由此组合成不同的标准目标态势类，并通过仿真得到标准目标方位序列集。将实测目标方位序列作为参考序列，标准目标方位序列集作为比较序列进行灰关联分析，得出与实测目标方位序列关联度最大的标准目标态势类，将此标准类反演即可得出目标运动要素。大量的仿真试验证实，该方法能在相对短的时间内得出一定精度的目标运动要素，从而实现线导鱼雷的远距快攻。

A Calculation Method of Target Motion Factors Based on Grey Relational Analysis

Aiming at the characteristic of fast attack from long distance for wire-guided torpedo, a method is presented which can quickly get the target motion factors based on grey relational analysis under an unmixed azimuth condition, According to proper division of initial target distance and velocity, as well as the board angles which are calculated via the variation of measured target bearing, different standard target classes are combined and different standard bearing sequences are obtained by simulation. Using the measured target bearing sequence as the refer sequence and the standard bearing sequences as the comparing sequences, the grey relational analysis is conducted to make sure that the target situation belongs to one of the standard classes, then the target motion factors are achieved. Simulation results show that the method can obtain the target motion factors with certain accuracy in a shorter time.
