Abstract

Precise InSAR is a new intelligent photogrammetric technology using the automatic imaging and processing means.It becomes the most efficient satellite-surveying-and-mapping (SASM) way that uses interferometric phase to create global digital elevation model (DEM) with high-precision.In this paper,we proposed the systematic InSAR technologies applied in SASM.Three key technologies are proposed.They are calibration technology,data processing technology and the post-processing technologies.Firstly,we need to calibrate the geometric and interferometric parameters including azimuth time delay,range time delay,atmospheric delay as well as baseline errors.Secondly,we have to use the calibrated parameters to create precise DEM.One of the important procedures in data processing is the phase constant determination.Finally,we improve the quality of DEM by jointly using block-adjustment method,long-and-short baseline combination method as well as descending-and-ascending data merge method.We use 6 TanDEM-X data that covers Shanxi to carry out the experiment.The root-mean-square error of final DEM is 5.07 m in the mountainous regions.And the area with low coherence is 0.8 km2.The accuracy meets the accuracy of China domestic SASM standard at 1∶50 000 and even the 1∶25 000 measurement scales.

Key words： InSAR; global mapping; calibration; post-processing; DEM
