Abstract :
Keliya River is in the hinterland of the Taklamakan desert. Revealing the distribution of the lower reaches of the fossil river has important significance for its ecological construction and groundwater source surveying. Using an X-band SLAR image as an important information source, and combing this with the field investigation, the fundamental principle and imagery feature of the river course in the airborne SLAR image are studied and analyzed. The study indicated that the X-band of the SLAR image could pass though 14.6 cm depth in the background desert, and 10.34 cm depth in the fossil riverbed
