摘　　要：相参诱偏技术,相对目前广泛采用的非相参诱偏技术,理论上可将反辐射导弹诱偏至导弹杀伤半径外的安全区域,具有一定的应用前景,其实现难点主要在于相位差的控制。通过两点源反辐射导弹诱偏模型,得出相参辐射源安全诱偏反辐射导弹所需要的相位差,提出利用交互多模-概率数据关联滤波估计的方法对反辐射导弹的位置进行滤波估计以减少相位差误差。仿真试验表明,该方法能有效提高定位精度,减少相位差误差。Coherent decoy technology can induce the antiradiation missile （ARM） to the safe area beyond kill radius of ARM compared with the widely used noncoherent decoy technology, and it has great importance in practicality, but the choke point of its utility is the phase difference control of radiations. The needed phase difference in safe coherent decoy is deduced through the model of two radiations deco- ying antiradiation missile, and then IMM-PDAF method is presented to estimate the location of ARM and reduce the phase difference error of radiations . Simulation results show that this method can improve the location accuracy of ARM and reduce the phase difference error effectively.
