| Abstract: | This letter presents a novel approach for the Synthetic Aperture Radar(SAR)stereo imaging based on the Capon spectrum estimation technique.In order to deal with nonuniform sampling space and lead to super resolution in the elevation direction,Capon approach is used to focus the SAR data on a certain height.Results obtained on simulated data demonstrate the feasibility of the Capon based algorithm.Compared with the classical Fast Fourier Transform(FFT),the Capon based algo- rithm shows better resolution quality. |
