Applications of Two-Dimensional FFT Algorithm in Radar Signal Processing of LFMCW Based on FPGA
摘要
Abstract
There is a certain degree of difficulty to detect moving targets by linear frequency modulated continuous wave( LFMCW) ,two-dimensional FFT target echo signal processing techniques to extract phase information,which can effectively suppress the fixed clutter,achieve the detection of moving targets. The implementation of signal pro-cessing for Doppler velocity radar with a FPGA chip and LFMCW Doppler radar signal processing principles are in-troduced. The data buffer,fast algorithm for the FFT sequence of real numbers,Hilbert transform,etc of the FPGA are described. Finally, the test results show that the two-dimensional FFT algorithm can extract the distance and speed of the target.关键词
