Abstract:

For the problem of strong anti-jamming ability of the netted radar system, a false target deception jamming optimized method is proposed in the context of the netted radar with a centralized fusion structure. First, the state and measurement model of the target of the netted radar, and the false target distance and velocity deception jamming model are established, and then the measurement deviation model is established. Next, based on this, the influence of the single and continuous false target deception jamming against the Kalman filtering state estimation error of the netted radar fusion center is studied respectively. Finally, by analyzing the false target deception jamming constraints, the optimization problem of the false target deception jamming objective function is proposed, which is solved based on the simulated annealing arithmetic. Simulation results verify the state estimation error expression caused by the false target deception jamming and the effectiveness of the proposed method.
