| 摘 要： | CFAR（ConstantFalseAlarmRate）算法通常采用DSP模块加软件实现方案，但窄脉冲雷达采用该方案存在电路规模大、结构复杂等弊端。本文依据CFAR算法运算量大但算法规则、简单的特点，提出一种全硬件实现方案。文中详细介绍了CFAR全硬件实现方案的原理、电路组成和各部分电路的设计方法，给出了硬件CFAN的性能指标和实物照片。

| Abstract: | The approash to CFAR is usually implemented by DSP module with software. However,this scheme has some shortcomings, that include large scale of circuits and complicated architecture etc, in narrow pulse radar. In this paper, an implementation of CFAR with pure hardware is proposed based on the characteristics os CFAR: large amount of calculation and simple rule.The principle of the implementation of CFAR, the configuration of circuits and circuit's design method of each section are described detailedly in this paper.The performances of the implementation of CFAR and the picture of prototype are shown. |
