A synthetic aperture processing system 10 includes a signal transmission unit 12 for generating a plurality of chirp waves and radiating the plurality of chirp waves to an irradiation region from a plurality of measuring sites, a signal reception unit 14 for receiving a plurality of reflected waves caused by the plurality of chirp waves radiated from the signal transmission unit 12, a range compression unit 15 for range-compressing each of the reflected waves received by the signal reception unit 14 and generating reception data consisting of a plurality of sinc functions, a cross-correlation computation unit 18 for, based on a plurality of model data segments consisting of a plurality of sinc functions obtained by range-compression of ideal reception waves caused by the reflection of the frequency-modulated waves at a plurality of predetermined sites in the irradiation region and the reception data generated by the range compression unit 15, calculating correlation values representing a degree of correlation between each of the model data segments and the reception data, and image output unit 19 for outputting the correlation values calculated by cross-correlation computation unit 18.
