针对高斯杂波背景,导出了MIMO雷达中CA-CFAR的虚警概率与检测概率的解析表达式,分析了CA-CFAR检测器在均匀杂波、多目标干扰及杂波边缘三种典型杂波背景中的检测性能。结果表明,CA-CFAR检测器在均匀杂波中性能较好,但在多目标干扰环境中性能严重下降。
Aimed at Gaussian clutter background, the analytical expressions of false alarm probability and detection probability of CA-CFAR detector in MIMO radar are given. The detection performance of CA-CFAR is analyzed under three typical clutter backgrounds such as uniform clutter, multi-target interference and clutter edge. The simulation results show the performance of CA-CFAR detector is good under uniform clutter, and is seriously descended under multi-target interference background.
