Abstract
This paper discusses spectral filtering for radar interferometry, especial the impact of the filters´ position in the processing procedure. After analysis, we get the best filtering process for interferometry which contains one time of azimuth filtering and two times of range filtering. Using this process, we can improve the coherence between image pairs greatly and get an interferogram with high quality.
