摘要

调频连续波（FMCW）雷达不易受云、雨、雾等天气因素的影响

可全天候工作

特别适合于港口起重机防撞系统等需要在恶劣的环境中进行短距离、高精度的测距。以8 mm FMCW雷达为研究对象

在深入研究了雷达输出中频信号特性的基础上

设计出了以数字信号处理器（DSP）为核心的信号处理电路

该电路通过完成对雷达中频信号的滤波、放大和快速傅立叶变换（FFT）分析

可以进行准确的测距。

Abstract

The FMCW radar is weatherproof and it can be used in high precision range finder of short distance

especially for the port crane crash preventing system.Based on 8 mm FMCW

the feature of the output signal from the FMCW is analysed.More than that

the details of circuit design for signal processing which is based on DSP is introduced.The circuit can measure precisely

while the signal is filtered

magnified and FFT is analysed.
