MCU+DSP的LFMCW雷达信号处理系统设计
LFMCW Radar Signal Processing System Based on MCU + DSP
摘要
Abstract
In the paper ,a scheme of LFMCW radar signal processing system based on C8051F120 + TMS320F28335 is proposed . C8051F120 is used as the signal acquisition core ,it generates the modulation voltage signal ,then drives the radar sensor to generate the beat signal ,and carries on the beat signal conditioning and gathering .TMS320F28335 is used as the signal processing core ,and the fre-quency estimation algorithm based on phase-frequency matching is embedded to process the beat signal to get the measurement .The on-line experiment results show that the functional modules work properly and the phase-frequency matching algorithm gains high precision .关键词
