基于攻击区匹配的机载雷达作战效能评估方法

Evaluation Method of Operational Efficiency based on Attack Envelope Matching for Airborne Radar

复杂电子对抗环境下机载雷达作战应用的不确定性,对其进行作战效能评估存在很大困难。提出一种基于攻击区匹配的机载雷达作战效能评估方法,该方法以无干扰条件下雷达对目标参数的测量值进行解算得到的火控攻击区为基准,计算相同作战态势下在干扰环境中我机机载雷达测得的受干扰参数解算得到的火控攻击区落在基准攻击区内的概率,以此攻击区匹配率作为评估准则对机载雷达的作战效能进行评估。通过实例仿真说明该方法能对机载雷达在体系对抗环境中的作战效能进行有效评估。

With the widely application of electronic warfare devices,the electromagnetic environment in battlefield becomes more and more complicated,resulting in many difficulties in evaluating operational efficiency of airborne radars.In this paper,a new method to analysis such operational efficiency is put forward,using tactical operation as the evaluation criteria.It is known that radar surveys the target and collects data of it,the fire control attack envelope can be found form the data.According to this method,when there is no interference,such a fire control attack envelope is regarded as a benchmark,then the possibilities of the fire control attack envelope gained in an environment with interference to fall into the benchmark is used to evaluate the operational efficiency of airborne radars.At last,the interference suppression capability of airborne radars is evaluated in our simulation.
