摘要：

Owing to the presence of relatively large amounts of noise, coregistration of synthetic aperture radar (SAR) images typically involves matching of local area baaed 'tie patches' rather than feature based 'tie points'. Some applications require small tie patch windows, e.g. stereo SAR. Small tie patch windows, however, can lead to poor estimates of the local co-registration parameters. A procedure to minimise the tie patch window size while retaining 'confidence' in the local co-registration result is proposed. Background theory to the procedure and the results of an experimental study are presented.
