Experimental estimation of phase noise filters efficiency for InSAR processing

Abstract

The experimental study of the efficiency of interferometric data processing algorithms for synthetic aperture space radars is complicated by the fact that a quantitative result can be obtained only after the completion of the entire technological chain. The efficiency of the first stages of interferometric processing - incoherent accumulation and suppression of phase noise-has been studied on the basis of the method of inverse transformation of standards previously proposed by the authors. The results of estimation of accuracy of digital elevation model construction for ALOS PALSAR data with different base lengths and polarizations of the probing signal are presented.
