Abstract
In a radar image processing device and a radar image processing method which can accurately extract a change of a ground surface, a communication interface unit () obtains a plurality of radar image data of a same observation target obtained at different times and stores in a radar image storage unit (), and a registration processor () reads the plurality of radar image data from the radar image storage unit () and registrates the radar image data with respect to each other. Then, a characteristic value calculating unit () calculates a plurality of characteristic values indicating a state of a ground surface which is the observation target based on the positioned radar image data. A change candidate region extracting unit () extracts change candidate regions for each of the characteristic values, and a judging unit () extracts a region of land cover change of the observation target from the change candidate regions using a threshold value, an extracting condition, and a judging function determined by a judgment method determining unit ().
