Detection of the Great Wall Using SIR-C Data in North-Western China
A segment of ancient Chinese Great Wall was imged by Shuttle Imaging Radar-C.The Wall is situated in the desert region and even partly buried in a thin and layer.SIR-C image reveals the whole segment of the wall.There are three walls imaged by SIR-C.Two were built in Ming Dynasty (1474 A.D.and 1531 A.D.) and one was built in Sui Dynasty (585 A.D.).Great Wall in Ningxia and Shanxi Province was made of loess soil taken from the local windblow sedimentary deposits.The Wall is seriously damaged by erosion.This paper presents the study on radar imaging mechanism of Great Wall, radar of the Wall in relation to the frequency and polarization.The study shows that the long wavelength,L-band radar image is better for detection the Wall, especially in sand covered area.Multifrequency, Multi-polarization SAR image is an effective tool for detecting the special historic remains, such as the Silk road, the ancients graves etc.
