USE OF CURVILINEAR SAR FOR 3-DIMENSIONAL TARGET FEATURE-EXTRACTION

The use of curvilinear synthetic aperture radar (CLSAR) is considered for three-dimensional feature extraction of small targets consisting o f a small number of distinct point scatterers. CLSAR does not suffer f rom the ambiguities suffered by interferometric SAR. As CLSAR is a rel atively new technology, a self-contained detailed derivation of the da ta model is presented. The Cramer-Rao bounds of the parameter estimate s are also derived. Use of the RELAX algorithm for 3-D target feature extraction with CLSAR for different curvilinear apertures is also desc ribed.
