Document Type and Number:
Japanese Patent JPWO2022190196
Kind Code:
A1
Abstract:
The change detection device 10 includes a three-dimensional structure reconstruction unit 11 which reconstructs a three-dimensional structure of a predetermined area in an observed area, a phase eliminator 12 which eliminates phase signals in the predetermined area in multiple SAR images in which the observed area is taken, using the three-dimensional structure, and a change detection unit 13 which generates a coherence image from a SAR image pair from which the phase signals are eliminated and detects change in the observed area based on coherence values of pixels constituting the coherence image.
