発明の名称 (英語) SYNTHETIC APERTURE PROCESSING SENSOR, PROCESSING METHOD FOR SENSOR, AND PROGRAM
発明の概要(英語) Provided is a synthetic aperture processing sensor that, with a simple configuration and in a short amount of time, enables extraction, from within a synthetic aperture radar (SAR) image, of a point (CS) which has little phase fluctuation and is stable, and that enables highly accurate atmospheric correction processing. The synthetic aperture processing sensor comprises the following: a storage section (33) for storing a plurality of reception data items which correspond to reflective waves sequentially obtained at a plurality of data acquisition positions within the movement range of an antenna (antenna section (10)) along the movement direction of the antenna; a resampling processing section (321) that generates first and second measurement data by resampling the plurality of reception data items; a SAR processing section (322) that conducts SAR processing on the first and second measurement data to generate first and second complex SAR images which include amplitude information and phase information; an interference image generating section (complex coherence processing section (323)) for generating interference images using the complex coherence between the first and second complex SAR images; and an extraction section (CS extraction section (325)) that extracts, on the basis of the interference images, an interference point (CS)(interference/scattering point) which is a stable point.
