Performance consideration of InSAR surface deformation monitoring


Abstract
We verified the detection accuracy as a sensor of ENVISAT/ASAR (C band) data. Moreover, we conducted time series analysis several times using high coherence image, and produced the stable time series by the polymerization effect. And I shortened the display color cycle, created the marginal image which can be sighted, and estimated the sensitivity of analysis image. As a result, a 0.4 mm color cycle was confirmed in Chiba City and the center of Tokyo. Since about (blue, yellow, purple, red) 4 colors can be clearly recognized in a color cycle, the sensitivity in Kanto district will be around 0.1 mm.
