Abstract

When using Fast Fourier Transform (FFT) to perform spectrum analysis on frequency modulated continuous wave (FMCW) radar signals, there are problems of barrier effect and spectral leakage. In order to keep away from barrier effect and improve precision of frequency estimation, we propose a method that apply the quadratic function method (QFM) to radar signal processing. The method quickly locates the maximum position of the spectral amplitude by the quadratic curve. The results of simulation and real data processing show that the method effectively solves the problem of the step effect of the distance and velocity estimation under the premise of only requiring adding a small amount of computations.
