Abstract
Azimuth compression processing is carried out by the steps of determining Doppler rate time change data a reconstructed scene from orbit data of a sattelite or aircraft, determining azimuth coordinates transformation data of an image after range compression, that is, resampling position designation data, from the Doppler rate time change data, resampling the image after range compression, in the azimuth direction using the azimuth coordinates transformation data, keeping unaltered the Doppler rate of a point image relating to the image after coordinates transformation irrespective to the position in the azimuth direction inside the scene, and thereafter using FFT.
