J. Li et al., USE OF CURVILINEAR SAR FOR 3-DIMENSIONAL TARGET FEATURE-EXTRACTION, IEE proceedings. Radar, sonar and navigation, 144(5), 1997, pp. 275-283
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.
