- The FMCW radar estimates the relative speed and the distance of moving targets from the frequency spectrum of received beat signal. The radar systems based on the Doppler processing measure the appropriate information from discrete frequency spectrum, and hence the accuracy depends on the sampling rate as well as the number of samples. In this paper, we propose the frequency offset estimation method based on the kernel function analysis. The proposed method can compensate the errors by using the fine beat frequency obtained from the accurate offset values. It provides the high accuracy with the less number of samples, so the system has lower computational complexity and higher speed processing compared with conventional methods.
