Based on three-channel SAR-GMTI system, the velocity and location of the deceptive moving target generated by single jammer are studied. Study result shows that both the deceptive stationary target and moving target can be considered as moving target, and the estimated azimuth location which has nothing to do with the setting value is the same as jammer.
A two-step convex optimization algorithm is proposed for array pattern synthesis with minimum number of antenna elements. Firstly, sparse array is synthesized based on convex optimization. Then, the optimized excitation coefficients exceeding the threshold are re-optimized again to obtain lower side lobe level. The non-uniform array and thinned array for the focused and shaped pattern have been investigated...
Synthetic aperture radar ground moving target indication (SAR-GMTI) has been extensively used in the battle field information acquiring. In this paper, a barrage repeater jamming against SAR-GMTI is proposed. This method separates the intercepted radar signal into several equal segments and reradiates them back to the radar in a rearranged order. The essence of the method is that the separation number...
Single-pass interferometric synthetic aperture radar (InSAR) has strong anti-jamming capacity, and can eliminate the arbitrary jamming generated by single stationary transponder via dual-channel cancellation. In this study, a novel three-dimensional (3D) deceptive scene generation method against single-pass InSAR based on two coherent transponders is proposed. The deceptive signal of the proposed...
