摘要
为评估电子对抗装备对光电搜索跟踪系统的干扰效果,针对光电搜索跟踪系统工作过程中的搜索、捕获、跟踪三个不同阶段,提出了相应的干扰效果评估方法。在光电搜索跟踪系统的搜索阶段和捕获阶段,分别依据实施干扰前后光电搜索跟踪系统的目标发现概率和捕获概率的变化来评估对系统的干扰效果。在跟踪阶段,以实施干扰后系统跟踪误差是否超出无干扰时正常跟踪精度的三倍来判定一次干扰是否有效,依据多次试验的干扰成功率来评估干扰效果和确定干扰效果的等级。
In order to evaluate the jamming effectiveness of electronic jamming devices on electro-optical search and tracking systems,three evaluation rules for the three working stages of electro-optical search and tracking systems are proposed.For the searching stage or capturing stage,the jamming effectiveness on an electro-optical search and tracking system is evaluated respectively according to the change of target detection probability or capture probability of the electro-optical search and tracking system after being jammed.For the tracking stage,whether the tracking error of the electro-optical search and tracking system under jamming is greater than three times its tracking accuracy when there is no jamming is taken as the criterion for whether the jamming is effective or not,and the jamming grade is determined according to the jamming success rate for numbers of jamming tests.
