摘要
恒虚警在着陆雷达系统中有着重要的作用和地位。恒虚警处理可以避免杂波变化影响检测阈值,提高雷达在各种干扰情况下的检测能力。文章首先介绍了恒虚警检测的原理,然后对几种典型方法进行了比较,选定单元平均选大恒虚警检测方法进行设计,并且实现了基于ADSP-TS201的恒虚警处理,最后通过Visual DSP++进行了仿真验证。
CFAR（Constant False Alarm Rate）plays an important role in the system of the PAR（Precise Approaching Radar）. It can prevent the test gate from the influence produced by the changing of the pigeons and improve the detectability of the radar. At first ,the paper introduces the principle of the CFAR,and then compares several typical methods. Then I choose the GO- CFAR to design and actualize the CFAR processing based on ADSP-TS201 . At last,I simulate the design with Visual DSP＋＋.
