An improved Image-Level simulation method for Spaceborne InSAR system is presented and realized under a precise InSAR geometry model. The fact that by using different simulation parameters the simulated interferograms shows different coherence is anayzised to find out how these parameters influence simulated interferogram and reasons for these influence are indicated in conclusions.
To study properties about land features information extraction of HJ-1A CCD1 remote environment monitoring images, this paper selected the east area of Nileke forest farm in western Tianshan mountains of China as the study area, used maximum-likelihood classifier, Mahalanobis distance classifier, minimum distance classifier and K-means classifier to classify, compare and analyze at two different scales...
Normally, in-orbit satellites are adopted in the satellite communication systems, which provide mainly high-rate data and voice transmission, such as Iridium system, International Maritime Satellite Organization (Inmarsat) system, and so on. When the satellites are close to the end of life, they will be pushed away from their original orbits and become space rubbish. However, if some special adjustment...
Geostationary satellite working life must take into account various factors. When it is close to the end of life, although the satellite payload will still be effective, the remaining fuel is not sufficient to maintain their positions of latitude, but only enough for keeping their station of longitude. If they can be used for slightly inclined geostationary orbit (SIGSO) satellite communication, their...
