摘　　要：针对传统杂波图在时变非平稳地杂波环境下检测虚警概率高的问题,提出了一种自适应门限的双参数杂波图检测方法,该方法利用杂波均值和方差的强度来自适应调整双参数杂波图检测门限中的加权比例系数,从而实现门限的自适应调整。试验数据分析结果表明:在复杂背景下,该方法在一定程度上能提高系统对虚警的抑制能力。To solve high false alarm probability of traditional clutter map in time-varying non-stationary ground clutter environment,an adaptive threshold two-parameter clutter map detection method is proposed.Using the intensity level of clutter mean and variance,the proposed method can adaptively adjust the weighted proportional coefficient in the detection threshold of the two-parameter clutter map,which realizes adaptive adjustment of the threshold.The experimental results show that in a complex background,the method can improve the system's ability to suppress false alarms to a certain extent.
