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。随着大规模集成电路，特别是高性能数字信号处理器的出现和数字信号处理技术在雷达信号处理中的广泛应用，如何在高性能数字信号处理器上高效地实现雷达信号处理算法成为雷达工程师需要着重研究的课题。首先介绍了数字信号处理芯片，ADSP21160的主要特点，然后讨论了瑞利分布杂波背景中雷达目标恒虚警检测的原理，最后着重阐述了基于数字信号处理芯片ADSP21160实现杂波背景中雷达目标恒虚警检测的方法和仿真实验结果。

CFAR detection of radar targets in heavy clutter background is an important part in radar signal processing. With appearance of LSI and high capability DSP, DSP technology is used in radar signal processing widely. How to realize signal processing effectively basing on high capability DSP is an important problem that radar engineers must consider. In this paper, the characteristics of ADSP21160 are introduced first, then the principle of radar CFAR detection in Rayleigh distributed clutter is discussed, and the way of realizing radar CFAR detection in clutter background based on ADSP21160 is proposed, and the results of simulation are provided at last.
