This thesis describes a new implementation of the JERS-1 (Japanese Earth Resources Satellite-1) Synthetic Aperture Radar(SAR) signal processing software. SAR, usually mounted on a satellite or airplane, uses the most elegant radar mapping technology.
Major difficulties with the SAR signal proceesing are in the huge computational burden, range cell migration effect especially in case of spaceborne SAR, and the doppler bandwidth variation caused by the satellite position error.
In this thesis, we propose algorithms for range cell migration compensation, doppler centroid estimation, which faciliates range cell migration compensation, azimuth compression, and hardware error compensation.
We have implemented a spaceborne SAR signal processing software in the X- window based environment with the enhanced user interface capability. Moreover, the package is built in modular basis to facilitate maintenance and subsequent modifications.
