Zusammenfassung: | A synthetic-aperture-radar-signal processing device includes a range bin selection unit which selects, from an observed image, range bins including a signal from an isolated reflection point, a phase evaluation unit which evaluates phases in an azimuth direction in the range bins, a window function multiplication unit which designs a window function on the basis of results of the evaluation by the phase evaluation unit and multiply the range bins by the window function, and a phase error correction unit which corrects the observed image by estimating a phase error from the range bins multiplied by the window function. |
