Abstract: For the active high fidelity decoy jamming generated by exo-atmospheric jammer, the decoys at the radar data processing level can be discriminated based on dynamics conversation law. That makes the conventional decoys invalidate to some extent. The correlative relationship among the active decoy parameters and the kinematics parameters is derived theoretically based on the moderate kinematics modulation principle. The relationship is simplified to a quadratic equation, and analytic expression is also derived. The countermeasure performances of the conventional false targets and the moderate modulated false targets are compared by computer simulation. The study illustrates that the kinematic characteristics of the active high fidelity decoys generated by the proposed method are the same as those of the true targets, achieving the purpose of mixing the false with the genuine.
