ABSTRACT:
In an SAR image processing system of the type wherein an image is reproduced from received data, the reproduced image is obtained on the basis of range compression, range curvature compensation and azimuth compression, the correlation coefficient between two look image signals is determined for each of predetermined relative shift amounts, the relative shift amount K.sub.max giving the maximum correlation coefficient is determined, and an azimuth reference function and range curvature compensation function are generated based on the shift amount K.
