An improved sar/gmti scheme using multiple-port interferometer
一种改进的多通道干涉SAR／GMTI方案

The principle of multiple-port interferometer SAR/GMTI is analyzed and the influence of various system errors on the capability for suppressing the main lobe clutter is also discussed in this paper, then the modification on the most critical weighting factor of this multiple-port interferometer is proposed. The theoretical analysis and simulation results show that this improved multiple-port interferometer SAR/GMTI scheme is insensitive to system errors or noise and is very robust, therefore it is suitable to be realized in the engineering.
