WebMay 26, 2024 · I have written a code in MATLAB to determine the range and doppler response of a single target for FMCW Radar. I am able to determine the accurate range of target after performing the first FFT. However, as I determine the 2nd FFT to get the Doppler response, the velocity is accurately determined. However, when I plot the contour map … WebAbstract: In this paper we propose a novel method for the mitigation of uncorrelated frequency-modulated continuous-wave (FMCW) automotive radar interferences based on the short-time Fourier transform (STFT) and L-statistics. The idea of the method is to compute the STFT of the beat signal and sort each constant frequency line of the …
