恒虚警性能分析及在DSP芯片上的实现

摘要

CFAR detection of radar targets in heavy clutter background is an important part in radar signal processing. But the research in the particular situation of airport is few. In order to provide a fit algorithm of CFAR. In this paper, first the principle of radar CFAR detection in Gauss distributed clutter ia discussed, then compared among four arrangements, the characteristics of ADSP- TS201 are introduced, and the way of realizing radar CFAR detection in clutter background based on ADSP-TS201 is proposed, and the results of simulation are provided at last.%强杂波背景中的雷达目标恒虚警检测是雷达信号处理的重要组成部分；在机场等特殊环境下的应用成为相关课题的研究对象；为了提供适于机场环境下的恒虚警处理算法,首先讨论了高斯杂波背景中雷达目标恒虚警检测的原理,然后对比分析了四种处理方案,并且介绍了数字信号处理芯片ADSP TS201的主要特点,针对机场环境阐述了基于数字信号处理芯片ADSP-TS201实现高斯杂波背景中雷达目标恒虚警检测的方法,最后采取机场实测信号实验结果验证,结果目标准确显示达到预期目标.
