The use of curvilinear synthetic aperture radar (CLSAR) is considered for three-dimensional feature extraction of small targets consisting of a small number of distinct point scatterers. CLSAR does not suffer from the ambiguities suffered by interferometric SAR. As CLSAR is a relatively new technology, a self-contained detailed derivation of the data model is presented. The Cramer-Rao bounds of the parameter estimates are also derived. Use of the RELAX algorithm for 3-D target feature extraction with CLSAR for different curvilinear apertures is also described
