摘要
A computer system (60)for registering synthetic aperture radar (SAR) images includes a database for storing SAR images to be registered, and a processor (69) for registering SAR images from the database. The registering includes selecting first and second SAR images to be registered, individually processing the selected first and second SAR images with an anisotropic diffusion algorithm, and registering the first and second SAR images after the processing. A shock filter is applied to the respective first and second processed SAR images before the registering. Elevation data is extracted based on the registered SAR images.
