A Fasle Moving Target Generation Method Based on Coherent Two-point Resouce

Focusing on the problem that the azimuth position is fixed and the radial velocity can not be controlled when the false moving target generated by the traditional two-dimensional shift-frequency jamming against the dual-channel Synthetic Aperture Radar-Ground Moving Target Indication (SAR-GMTI), a new type of false moving target generation method with shift-frequency modulation based on the cooperation of dual jammers is proposed. This method uses two-dimensional shift-frequency modulation to control the position of the false target and uses dual synergetic jammers to control the radial velocity of the false moving target. The dual jammers coordinate through the amplitude and phase modulation coefficients, which can be solved by solving linear equations. In this paper, the limitation of single jammer shift-frequency jamming against dual-channel SAR-GMTI is analyzed, the dual jammer cooperative deception jamming model is introduced, the method for solving amplitude and phase modulation coefficients is explained, and the steps of generating false moving targets is given. Theoretical analysis and simulation experiment verify the effectiveness of the proposed method. And in the process of generating false moving targets, only two-dimensional shift-frequency modulation is used, so the method is relatively simple to achieved, and can offer certain reference value for practical engineering applications.
