| 摘 要： | 雷达信号的恒虚警检测是雷达信号处理的重要组成部分.首先阐述了两种基本检测器的原理与性能,以及针对实际情况所采用的恒虚警处理技术.在此基础上,利用ADS(advanced design system)仿真技术建立某星载雷达接收机模型,模拟回波信号经过接收机的工作情况,通过蒙特卡罗仿真法对输出信号进行噪声恒虚警检测,获得了更接近真实环境的检测曲线并对其进行分析,为进一步研究雷达系统性能提供了参考.

| Abstract: | The constant false alarm rate(CFAR) detection of radar's signals plays an important role in radar signal processing.Firstly,this paper describes the theories and properties of two kinds of basic detectors,as well as the technology of CFAR related to real noise condition.Based on this,a spaceborne radar receiver model was built using ADS to simulate the working condition of radar echo when passing,and through Monte-Carlo simulation,its output signal was detected with CFAR technology.Finally,the more accurate... |
