Patent ID: 8421669

Claim:
A synthetic aperture processing system comprising; transmission means for generating a frequency-modulated wave having a time-varying frequency and radiating the frequency-modulated wave to an irradiation region from a plurality of measuring sites; reception means for receiving a plurality of reflected waves caused by the plurality of frequency-modulated waves radiated from the transmission means and reflected off objects in the irradiation region; range compression means for range-compressing each of the reflected waves received by the reception means and generating reception data consisting of a plurality of sinc functions; correlation value calculation means 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 means, calculating correlation values representing a degree of correlation between each of the model data segments and the reception data; and output means for outputting the correlation values calculated by the correlation value calculation means.
