COMPARISION OF URBAN BACKSCATTER CHARACTERISTICS OF MULTITEMPORAL ALOS PALSAR IMAGES

The aim of this paper is to describe and analyze the polarimetric backscatter characteristics of different urban land surface fecatures using multitemporal L-band SAR images. For this purpose, multitemporal polarimetric ALOS PALSAR images of Ulaanbaatar, the capital city of Mongolia have been used. For the analysis, the backscatter values of a group of contextually dependent pixels selected from different parts of the images presented in digital numbers have been used. The results are discussed and some explanations on findings are given.
