ABSTRACT:
A feature referenced error correction apparatus utilizing the multiple images of the interstage level image format to compensate for positional displacement errors in the synthetic aperture radar imaging. Error compensation is accomplished through the registration of key features of sub-aperture images and by the generation of an error correction signal in response to the sub-frame registration errors.
