北斗系统支持下基于态势特征图的反舰导弹目标选择方法

Target selection method of anti-ship missile based on situational feature map supported by Beidou system

针对复杂背景条件下反舰导弹预定目标选择的问题,提出了在北斗系统支持下基于态势特征矩阵匹配(SFMM)的目标选择方法。首先,定义了包括目标位置、速度及其类型等信息的态势特征矩阵,利用防空导弹目标实物图(TOM)理论,将SFMM问题等价为目标选择的指派模型;然后,考虑到反舰导弹态势特征矩阵相对防空导弹变化缓慢,利用北斗系统短报文功能实现了对态势特征矩阵的适时更新;最后,仿真实验分析了指挥系统误差、制导雷达精度、目标机动速度等对SFMM方法的影响,给出了态势特征矩阵更新间隔,并与Hausdorff距离匹配方法进行了对比。结果表明:在观测设备误差相同情形下,SFMM的选择正确率更高,说明该方法可以有效地解决复杂背景下反舰导弹的预定目标选择问题。

In order to solve the problem of anti-ship missile predetermined target selection under complex background conditions,a target selection method based on situational feature matrix matching(SFMM)was proposed with the support of Beidou system.Firstly,the situation feature matrix including target position,velocity and type was defined,and the SFMM problem was equivalent to the assignment model of target selection by using the TOM theory.Then,considering that the anti-ship missile situation feature matrix changes slowly compared with that of anti-aircraft missile,the Beidou system short message function was used to update the situation feature matrix timely.The simulated calculation further analyzed the command information system error,the accuracy of the anti-ship missile terminal guidance radar as well as the target maneuvering speed influence on SFMM methods,and updated interval of situation feature matrix was given.Compared with the Hausdorff distance ma-tching method,in the case of the same error of the observation equipment,SFMM selection accuracy is higher,which shows that the method can effectively solve the problem of intended target selection of anti-ship missile under complex background.
