<p>PROBLEM TO BE SOLVED: To solve the problem that an S/N ratio becomes bad and the estimate accuracy of a phase error is deteriorated when there are many isolated points or there are no projected isolated points and a receiving level is weak as a whole in a conventional synthetic aperture radar signal processor. SOLUTION: A plurality of isolated points are extracted from a processed SAR regenerated image and, after zero filling processing is applied to all of the extracted isolated points, the phase error related to the isolated points is calculated and a phase is compensated using the phase error highest in frequency distribution.</p> |
