Implementation of a SAR GeoCoding Module based on component

摘要

Abstr act: This paper describes the SAR geocoding module,rnwhich is the sub-module of a IRHIS ("Integrated RS s/w forrnHigh resolution satellite ImageS"): package of "Developmentrnof High Resolution Satellite Image Processing Technique"rnproject in Electronics and Telecommunications Research Institutern(ETRI).rnThe function of this module is following.rn1) Orbit Type : ERS1/ERS2, RADARSATrn2) Data Format : SAR CEOS Format(Single Look Complex)rn3) Function:rn- Geocode : Generate a map projected SAR image based onrnonly orbit informationrn- Orthorectify: Generate a rigorous geocoded SAR image withrna DEM informationrnIn this paper, we briefly describe the algorithm that isrnadopted to the functions, and component architecture.
