摘要

差频信号采集系统是线性调频连续波（LFMCW）雷达的核心部件之一。针对国产某新型LFMCW雷达传感器

设计并实现了基于C8051F120的LFMCW雷达差频信号采集系统

包括调制信号产生模块、差频信号采集模块以及串口通信模块。主要实现的功能有:产生非线性校正后的锯齿波调制信号;采集雷达差频信号并搭建二阶有源带通滤波器进行放大滤波;发送差频信号至上位机等。实验验证了LFMCW雷达差频信号采集系统的有效性。

Abstract

Beat signal acquisition system is one of the core components of linear frequency modulated continuous wave（ LFMCW） radar. A LFMCW radar beat signal acquisition system based on C8051F120 is designed and implemented for a new LFMCW radar sensor

which includes modulation signal generation module

beat signal acquisition module and serial communication module. It can complete the functions such as the generation of nonlinear correction of the sawtooth wave modulation signal; radar beat signal acquisition and build a second-order active bandpass filter for amplification; sending beat signal to the host computer and so on. The experimental results verify the effectiveness of the LFMCW radar beat signal acquisition system.
