| 摘 要： | 杂波背景中区分出有用目标回波的恒虚警(CFAR)检测技术,是直接影响雷达性能的关键技术之一。主要研究了CFAR检测的基本理论,重点研究了ML类CFAR算法中的邻近单元平均恒虚警(CA-CFAR)的检测算法,推导了其检测概率和虚警概率表达式,通过计算机仿真比较了在不同窗长情况下的检测门限。

| Abstract: | The CFAR detection technology which can differentiate the target echo pulse from the clutter is the key technology of the radar performance. The basic theory of the CFAR specially the CA-CFAR detection algorithm is studied, the formula of the false alarm and the discovery probability are deduced, and the threshold coefficients for different window length are compared by the simulation. |
