雷达在不同杂波背景下的恒虚警率处理

The Constant False Alarm Rate Processing in Radar Different Background

雷达工作在复杂多变的杂波环境中,自适应地选择一种与雷达工作环境匹配的恒虚警率检测器,是恒虚警处理的核心。文章主要论述符合高斯分布的噪声和杂波背景下,几种典型恒虚警检测器的优缺点、适用环境;并结合工程实践经验给出各类恒虚警门限的优化设计原理,提出了在不同环境下的最优恒虚警检测处理流程。

Radar works in a complex clutter environment, self-adaptive selection of optimal type of CFAR(Constant False AlarmRate) detector in different environment is the core of CFAR processing technology. This paper discusses the advantage and disadvantage of several typical CFAR detector, and the suitable environment in Gaussian disturbing background. Combined with engineering practice experience, we propose the optimal design principle of all kinds of CFAR threshold, at the same time, propoundthe optimal CFAR detection processing under the different environment.
