Abstract
Vegetation growth condition analyzer, method and record medium using plural radar imaees of a ground surface of a same target area, which have been laken at multiple times during the year obtained from a flying body, e.g. an artificial satellite are disclosed. These images are stored in a map database and aligned wjth a criterion image. Extracting a backscatter coefficient of a specified target area in the criterion image from the map database and calibrating the backscatter coefficients of other radar images are entailed. Finally, calculating growth values of vegetation shown in the radar images by use of the calibrated backscatter coefficients are obtained.
