Abstract

The problem of registering a reconnaissance side-looking synthetic aperture radar (SAR) image to a three-dimensional reference map is examined by developing a technique which is based on computing an image-to-date base correspondence in terms of a SAR sensor model as a function of such parameters as altitude, range, scale, etc. If their exact values are known, registration is accomplished by utilizing the model to predict the two-dimensional image coordinates for any three-dimensional data base point. In general, the platform ephemeris (PE) data provides only coarse model parameter estimates. The objective, then, is to refine them so that the model can predict the image location of any data base point within a desired accuracy range. The results obtained in this paper demonstrate the feasi-bility of achieving location accuracy within 50 m.
