Abstract
This signal processing device comprises a simulated SAR image generation unit and an evaluation calculation unit. The simulated SAR image generation unit generates simulation information including: a simulated SAR image formed from prediction values of pixels predicted to be obtained when a target region is observed in a steady state; and prediction reliability information indicating the reliability of the prediction values of the pixels. The evaluation calculation unit uses the simulation information to determine the evaluation index whereby a target SAR image, which is an analysis target, is evaluated.
