目标散布区对导弹目标选择概率影响的仿真模型

当反舰导弹飞近目标散布区时,导弹搜索雷达必须开机搜索目标,导弹根据目标反射信号的几何或能量特性,利用某一算法从被探测到的,包括敌方施放的假目标在内的所有目标中选择某一目标作为导弹的攻击目标.目标散布区的外形和大小对导弹选择真实目标概率的影响是一个尚未得到深入研究的问题.推导了目标散布区对导弹正确选择目标概率的影响函数;在考虑了目标舰及时提供假目标的仿真模型的基础上,给出了七种导引头选择目标的算法及仿真模型.仿真结果表明,目标散布区影响反舰导弹雷达的开机时间,从而影响导引头选择真实目标的概率及其抗电子干扰能力.

Simulation Models on the Influence of the Target Distribution area on the Target-Choosing Probability of Anti-ship Missile

When anti-ship missile approaching the potential distribution area of the target, the search radar of the missile starts to search target.Based on the geometric or energy reflection characteristics of target,the missile employs some algorithm to choose one target for attack among all the detected targets,including the deployed decoys.The influence of the shape and size of the target distribution area on the probability of the missile choosing the true target has not been well investigated.In the paper,the influence function of the area on the target-choosing probability is deduced.Based on the model of the timely decoys deployed by the goal ship,it presents in the paper seven target-choosing algorithms and the according simulation models.From the simulation results on the models it shows that the target distribution area will significantly influence the starting time of the missile radar, therefore influence the probability of true target choosing and the anti-jamming capability of the missile seeker.
