摘　　要：为简化描述脉冲积累数、雷达参数及目标后向散射截面与发现概率、虚警概率之间的关系,结合伪装效果检测情况,提出了一种评价目标伪装前后雷达发现概率的方法,即构建评价函数对上述关系进行特征逼近研究。结果表明,该评价函数能反映伪装前后目标RCS与背景RCS比值的变化规律,且计算过程简单,可用于雷达检测评估。In order to describe briefly the relation of pulse accumulation number, radar parameters, target RCS and detect probability, false alarm probability, by making use of the instance of camouflage effect detection,a method is put forward to evaluate radar detection probability for targets of fore - and - aft camouflage. Then an evaluate function is constructed to approach characteristics of relation function above. Result shows the evaluate function can indicate variety rules about the ratio of target RCS to background RCS, and that operation is simple. Thus the method can be used to evaluate radar camouflage effect.
