Inducing Anti-Radiation Missile Safely under Coherent Decoy Based on VD-Kalman Filter

Coherent decoys can induce anti-radiation missile (ARM) to the area outside radiant sources compared with the noncoherent decoys technology widely used now, the choke point of final utility of coherent decoy is the accurate control of radiant sources´ phase difference. Model of two radiant sources decoying ARM is built in this paper, relationships between the phase difference of two coherent radiant sources and the factors of radiant sources are analyzed. Combined with the ARM movement model, a data processing method -VD-Kalman filter is proposed to improve the location precision of ARM, which can decrease the phase difference error effectively. Simulation results demonstrate the effectiveness of the method.
