| 摘 要： | 文中研究Pearson杂波背景下的CFAR检测问题。推导出CA、GO和SO三种CFAR检测器在Pear—son分布杂波背景下虚警概率的初等函数表达式，证明了它们在Pearson分布杂波背景下仍具有恒虚警性能。全面分析了这三种均值类检测器在均匀背景和非均匀背景下的性能。结果表明SO-CFAR在均匀背景和多目标干扰情况下均具有最好的检测性能，而GO-CFAR则在杂波边缘情况具有更好的虚警控制能力。

| Abstract: | The problem of constant false alarm rate(CFAR) detection under Pearson distribution clutter is studied in this paper.We derive the exact elementary expressions of probability of false alarm for cell averaging(CA)-CFAR,greatest of(GO)-CFAR and smallest of(SO)-CFAR in homogenous background,and prove that these detectors are also of CFAR.The performance of these detectors are evaluated both in homogeneous and non-homogeneous clutter.The results show that the SO-CFAR has the best detection performance against u... |
