Abstract
A procedure is presented in the stereo matching of digital synthetic aperture radar (SAR) imagery obtained from NASA's shuttle imaging radar B (SIR-B) experiment. The coherent nature of SAR means that speckle is an inevitable by-product. The presence of speckle in SAR imagery makes the conventional use of region growing stereo-matching algorithms untenable. To overcome the problem of speckle, a technique was developed whereby stereo matching was performed in a course-to-fine pyramidal fashion. It is shown that the stereo-matched extent obtained with this technique can give an approximate three-fold increase in stereo coverage, if a suitable speckle-reduction filter is also employed.Keywords
