Feature extraction of a single dihedral reflector from SAR data
1997 IEEE International Conference on Acoustics, Speech, and Signal Processing
As one of the key steps in the feature extraction of targets consisting of both trihedral and dihedral corner reectors via synthetic aperture radar, this paper studies the problem of estimating the parameters of a single dihedral corner reector. The data model of the problem and the Cram er-Rao bounds (CRBs) for the parameter estimates of the data model are presented. Two algorithms, the FFTB (fast Fourier transform based) algorithm and the NLS (non-linear least squares) algorithm, are deviseddoi:10.1109/icassp.1997.604856 dblp:conf/icassp/LiuL97a fatcat:js2jpgzx3fcfzdycd3jbd3zpri
