摘　　要：恒虚警(CFAR)处理技术是雷达自动检测系统中控制虚警率最重要的手段。文章首先对恒虚警检测原理进行论述,并给出三种适用于船用导航雷达信号检测的恒虚警处理技术,然后进行模型建立和算法仿真分析。最后在此基础上,针对于杂波边缘环境下,选取处理效果较好的恒虚警处理算法,利用现场可编程门阵列(FPGA)进行硬件实现,并给出系统的实际测试效果图。结果表明,整个系统具有较好的检测性能。The constant false alarm rate （CFAR） processing is the most important measure in controlling false alarm rate in the automat- ic detection system of radar. The CFAR detection theory and three CFAR processors, which are applied to marine navigation radar signal de- tection, are discussed in the article at first. Secondly, their mathematical models are established and algorithm simulation is analyzed. Final- ly, on that basis, the better CFAR processor algorithm is chosen in the context of clutter edge. It is carried out in Field--Programmable Gate Array （FPGA）. And the test result figures of system in practice are given. The result shows that the whole system has well detection per- formance.
