摘要
雷达信号的恒虚警率(CFAR)处理是现代雷达信号处理的重要内容。文中介绍了在杂波、噪声中检测目标的基本原理,并用参量CFAR检测方法分析了以瑞利杂波条件为例的恒虚警性能,最后给出了某新型火控雷达恒虚警电路的具体实现方法。
The eonstant false alarm rate (CFAR) processing of radar signal is an important item of modern radar signal processing. This paper introduces the basic target detection theory in the complicated noise environment and analyses the constant false alarm performance in Rayleigh noise environment by using parameter detection method. At the same time this paper also presents a detailed realization method of CFAR circuit for a kind of radar.
