摘要

High-precision DEM can be generated by SAR interferometry processing with GaoFen-3 repeat-pass data. This paper presents the first results from GaoFen-3 SAR Interferometry obtained with two interferometric SAR data pairs at the selected experiment sites. The temporal separations were 29 days. At the site the coherence requirements were met, resulting in high quality interferogram. The experimental results show that GaoFen-3 repeat-pass data have some good characteristics, such as high imaging quality, stable spatial baseline, high temporal correlation and spatial correlation, which has a good repeat-pass SAR interferometry application prospect.
