摘要
该文在考虑4臂平面等角螺旋天线双通道幅相组合测向系统工作原理的基础上,确立了测向系统在雷达诱饵合成场中导引信号形成模型,给出了一种简化的反辐射导弹运动模型,获得了分析诱偏效果的计算公式、动态仿真方法及模拟结果。数值计算表明,对于雷达诱饵之间距离为250m到300m的情况,通过合理设置诱饵电平可以使雷达及诱饵获得较高的生存概率,而诱饵辐射场初始相位对雷达诱饵生存概率影响相对较小。
Considering the mechanism of two-channel direction-finding systems with four-arm spiral antenna,guidance signal generation model related to the superposed field radiated by the antennae of radar and decoy is presented.A simple and practical movement model of Anti-Radiation Missile（ARM） is introduced.The dynamic simulation methods and formulae for analyzing deception effect are proposed.The simulation results show that high survival probability of the radar and the decoy can be achieved if the decoy level is set to some appropriate values when the distance between the radar and the decoy is set to 250-300 m,and the initial phase of the decoy radiation field has relatively less effect on the survival probability.
