本文研究单元平均检测器在高斯杂波背景、x~2目标模型、多目标环境中的检测性能。得到了检测概率和虚警概率的一般表达式和道推计算公式。针对参考单元中的干扰目标对检测概率的抑制效应,提出了二中择小修正型方案。并针对Swerling目标模型进行了理论分析,结果表明,方案能较圆满地解决这一问题。
In this paper, the detection performance of element average detector in Gaussian clutter background, x ~ 2 target model and multi-target environment is studied. The general expressions of the probabilities of detection and false alarms are obtained and the formulas for the calculation of the push-push are obtained. Aiming at the restraining effect of the interference target on the detection probability in the reference unit, a scheme of small two-choice small correction is proposed. The theoretical analysis of Swerling target model shows that the solution can solve this problem satisfactorily.
