Title:
合成開口レーダ信号解析装置、合成開口レーダ信号解析方法および合成開口レーダ信号解析プログラム
Document Type and Number:
Japanese Patent JP7006781
Kind Code:
B2
Abstract:
A synthetic aperture radar signal analysis device 20 includes: an extraction unit 21 that extracts a stable reflection point from time-series data acquired through observation, by a synthetic aperture radar, of a region to be observed from a predetermined observing direction; a generation unit 22 that generates a cluster which is a collection of stable reflection points on the basis of the extracted stable reflection point corresponding to the predetermined observing direction; an association unit 23 that associates the generated cluster corresponding to the predetermined observing direction with a structure indicated by map data corresponding to the region to be observed; and a synthesis unit 24 that performs vector-synthesis of displacement rates for a plurality of the clusters each corresponding to the observing direction associated with the structure.
