地面反射干扰抗反辐射导弹技术探索研究

Exploratory Study on Image-Jamming Against Anti-Radiation Missile

针对抗反辐射导弹问题,提出了一种新型地面反射干扰抗反辐射导弹技术。基于干扰功率模型、地面电磁散射模型、被动导引头测角模型和反辐射导弹运动模型,建立了地面反射干扰抗反辐射导弹全过程仿真模型。通过仿真计算,研究了地形和布站条件对地面反射干扰效果的影响。仿真结果表明:通过合理选择反射地面和合理设置地面反射点与被保护雷达的间距,地面反射干扰可以诱偏反辐射导弹,有效保护雷达辐射源。

A novel image-jamming technology against anti-radiation missile（ ARM） is demonstrated.Based on the model of jamming power,radar electromagnetic scattering patterns of earth surface,angle measurement of passive seeker and terminal trajectory of anti-radiation missile,the model of image-jamming against anti-radiation missile is established. By simulation calculation,the influence of ground reflection characteristics and laying form on the jamming effectiveness are discussed. Simulation results show that image-jamming can decoy anti-radiation missile,and protect radar source effectively,by reasonably selecting reflecting earth ground and laying the distance between reflection point and radar.
