Large, slow moving landslides in the Berkeley Hills cause costly damage and pose a potential threat to public safety due to the close proximity of the Hayward Fault. Now in the Berkeley Hills there are four large, slow moving, deep-seated landslides. All the landslides extend through residential areas and move on the order of cm/year, each covering an area(More)
Formation flying orbit design is one of the key technologies for system design and performance analysis of the distributed SAR satellites. The approximately analytic solution of the passive stable formation flying orbit elements is explored based on the expansion form of Kepler’s equation. A new method of orbital parameters design for three-dimensional(More)
In this paper, the information theory is utilized to evaluate the jamming effect on SAR. Entropy could reflect the spatial detail information, and cross entropy could show the divergence and discrimination information of the two kinds of probability distribution. We investigated the cross entropy and presented the improved cross entropy as an index to(More)
Spaceborne Synthetic Aperture Radar (SAR) interferometry is a powerful tool for measuring ground movements by exploiting phase difference of SAR images taken at different time. It has been successfully used in studying earth processes such as volcano deformation, tectonic deformation, and land subsidence but rarely applied in landslides. In this paper we(More)
Because the stability of plane platform is not good, airborne SAR can not acquire the precise orbit parallelism and velocity as spaceborne SAR. Motion Error problem for airborne formation flying InSAR is analyzed here. The plane interval changes (across track baseline changes) can be discussed in three situations: interval increasing, interval decreasing,(More)
Some discrete Fourier kind transforms (DFKT) which include the discrete Fourier transform (DFT), discrete chirp Fourier transform (DCFT), three-order discrete chirp Fourier transform (TDCFT), discrete matched transform based on phase compensation (DMTPC) are studied in the symmetric alpha-stable ( SalphaS ) noise environment. Some DFKTs based on the(More)
