高精度调频连续波雷达测距算法的研究
Research on high precision FMCW radar ranging algorithm
摘要
Abstract
In FMCW radar ranging algorithm,the error of spectrum analysis of FFT algorithm is caused by the interval between FFT spectrum lines.Therefore, in order to improve the ranging precision of FFT algorithm, reduce the error of the frequency spectrum analysis, the messures about the improvement of frequency shift compensation are proposed.Using spectrum symmetry and the distance between the adjacent two spectral lines point coordinates to get the spectrum shift of frequency shift compensation factor.The results of simulation experiments show that the measures can get the most value which is closer to the actual peak by wasting a little time.And it can improve the ranging precision of radar better.关键词
