Point quality evaluation results. (a) Results based on our proposed matrix in frequency domain; (b) results based on the previous matrix in time domain. The four subfigures in both (a) and (b) stand the three-dimensional surface, contour image, range profile, and azimuth profile. The two-dimensional and one-dimensional Fourier interpolations are used, and the times of interpolation are 64 and 1,024.
