Abstract
A synthetic aperture processing system that includes a signal transmission unit for generating and radiating a plurality of chirp waves to an irradiation region from measuring sites, a signal reception unit for receiving a plurality of reflected waves caused by the plurality of chirp waves, a range compression unit for range-compressing each of the reflected waves and generating reception data consisting of sinc functions, a cross-correlation computation unit for, based on a plurality of model data segments, calculating correlation values representing a degree of correlation between each of the model data segments and the reception data, and image output unit for outputting the correlation values calculated by cross-correlation computation unit.
