摘要： The signal processing device 10 includes a three-dimensional information with reliability reconstruction unit which generates three-dimensional information with reliability including three-dimensional information involving intensity and an estimated value of a phase at a three-dimensional position reconstructed using observed SAR images and imaging conditions, and information indicating reliability of the three-dimensional information, and a phase signal estimation unit 12 which calculates phase signals for all pixels in an analyzed area for all imaging conditions of SAR images to be analyzed, and calculates the information indicating reliability of the phase signals based on the information indicating reliability of the three-dimensional information.
