Short Range LFMCW System for Automobile Reversing Radar

摘要

A 77GHz LFMCW (Linear Frequency Modulated Continuous Waveform) radar system for automobile reversing application is presented. To improve the radar accuracy of distance and speed, several algorithm techniques such as variable-cycle triangle wave, combined amplitude and phase algorithm are introduced. And the radar can work under the influence of interference because of the clutter map technique. The radar system has been verified by Matlab.
