针对Weibull杂波背景下延展目标的恒虚警率(CFAR)检测问题,研究了三种积累检测器———二进制积累检测器、非相参积累检测器和秩积累检测器。首先在单脉冲情况下分别从理论上导出了这三种检测器均满足CFAR性以及对应的检测性能解析式,然后将单脉冲条件下CFAR方法推广到多脉冲积累情况,给出了四种可能的处理方案。最后仿真结果验证了理论分析的正确性。
Aiming at CFAR detection of extended targets under Weibull clutter, three kinds of accumulation detectors, binary accumulation detector, non-coherent integration detector and rank accumulation detector, are studied. First of all, in the case of single pulse, the three kinds of detectors are respectively theoretically derived to satisfy the CFAR property and the corresponding analytical performance analysis formula. Then the CFAR method under the single pulse condition is generalized to the multi-pulse accumulation situation, and four possible Treatment program. The final simulation results verify the correctness of the theoretical analysis.
