Abstract :
Airborne radar altimetry sometimes records abnormal phenomenon. In this case, information of real terrain must be incorporated to analyze the abnormality region. This paper applies terrain information of a test area organized by a spatial geographical information system (GIS) to the radar signal analysis. With the support of Global Positioning System (GPS) and Inertial Navigation System (INS), we can simulate the radar altimeter data by organizing and analyzing three-dimensional terrain information inside of the radar beam.
