摘　　要：研究Pearson分布混响背景下恒虚警检测器设计问题,提出2种具有多目标干扰抑制能力的OSGO(排序选大)和OSSO(排序选小)检测器,验证两类检测器的恒虚警特性,并分别推导虚警概率和检测概率的数学表达式。仿真结果表明,OSSO检测器具有最好的抗多目标干扰能力,OSGO检测器与OS检测器性能相近。2种检测器计算复杂度相比,OS检测器均降低一半。The problem of designing CFAR detector under Pearson-distributed reverberation is studied in this paper. Two kinds of CFAR detection scheme called OSGO and OSSO with multi-interrupt- target suppression ability are proposed here, the constant false alarm rate property of the detectors is proved, and the mathematic expressions of false alarm rate probability and detection probability are derived. The numerical simulations prove that OSSO shows best performance under multiple interruption target environment,OSGO owns similar performance with OS. Both OSGO and OSSO detectors just need one half computation cost compared with OS.
