Abstract: A map information update support device includes a communication interface unit that acquires plural items of radar image data of the same observation area acquired at different times, respectively, a registration processing unit that registrates the plural items of radar image data with respect to one another, a characteristic value calculation unit that calculates a characteristic value representing a state of a surface of the earth in the observation area using the items of radar image data after the registration process, a feature changed area extraction unit that extracts a feature changed area based on the characteristic value, a road change candidate area extraction unit that synthesizes the feature changed area with map information of the observation area and extracts a road change candidate area that is a candidate of a road changed portion, and an output unit that outputs the map information synthesized with the road change candidate area.

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 (10) obtains a plurality of radar image data of a same observation target obtained at different times and stores in a radar image storage unit (12), and a registration processor (14) reads the plurality of radar image data from the radar image storage unit (12) and registrates the radar image data with respect to each other. Then, a characteristic value calculating unit (18) 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.
