分析了对角加载自适应匹配滤波器(diagonally loaded adaptive matched filter,DL-AMF)和对角加载自适应相干估计器(diagonally loaded adaptive coherence estimation,DL-ACE)的检测性能；推导了二者的渐近统计分布,得到了解析的虚警概率(probability of false alarm,PFA)和检测概率(probability of detection,PD)表达式.与常规AMF和ACE相比,尤其是在训练样本不足的情况下,DL-AMF和DL-ACE的检测性能大为提高,并且二者都具有渐近恒虚警(constant false alarm rate,CFAR)特性.
