基于选择点的预定目标选择方法原理及性能

反舰导弹末制导雷达的目标选择方法主要采用"先入为主"和"录取对比"方法。从影响目标选择的误差因素出发,对这两种目标选择方法的原理进行了分析研究。研究表明:这两种方法都是基于选择点的预定目标选择方法;且由于受自控终点散布误差和目标机动误差的影响,基于选择点的预定目标选择方法不适应超视距应用。蒙特卡罗仿真表明,预定目标上释放冲淡干扰时,基于选择点的预定目标选择方法已基本不具备预定目标选择能力,超视距情况下正确选择预定目标的概率低于0.2。

Principle and Performance of the Target Selection Method Based on Selected Point

Two target selection method,"first capture is the designated target" method and "recording then comparing" method,are mostly adapted for ASM with terminal guidance radar.The principle and performace of the two methods are studied by analyzing the error factors involved.This two method can be regarded as "target selection method based on selected point",or "selected point method" for short.The performance of selected point methods is poor while applying to over-the-horizon ASM,because they are influenced by terminal dispersion of self-control phase and maneuvering error of target.Monte Carlo experimnets resulets show that selected point method is not capable to select the designated target while interferences exist,and the probability to select a designated target which is over-the-horizon of ASM launch platform is less than 0.2.
