| Abstract: | The problem of false target discrimination is studied based on synthetic aperture radar (SAR) with ground moving target indication (GMTI) capability. The interferometry phase characteristics of target signals and jamming signals are analyzed based on the principle of false target jamming and moving target detection techniques. Two kinds of robust indentation are extracted according to characteristics difference of the real and false target. A discrimination algorithm of deception jamming based on the interferometry phase is proposed in the paper, the process flow of the discrimination algorithm is given, and the application conditions and the computation complexity are also presented. Finally, the simulation experiment is carried out. Theoretical analysis and simulation results verify feasibility and effectiveness of the proposed discrimination algorithm. |
