摘　　要：为解决传统反辐射攻击仿真模型难以评价复杂地形下雷达诱饵的防护效能问题,基于反辐射攻击理论和复杂地形条件,对传统仿真模型进行改进.根据反辐射导引头与诱饵的位置关系,比较信号俯仰角与该方向上山体坡度大小,进而判断导引头和诱饵是否通视,从而完善反辐射攻击过程的动态判决条件,实现了对复杂地形下雷达诱饵防护效能的分析评价.仿真结果表明,在复杂地形下利用诱饵来抗反辐射导弹攻击时,诱饵采用菱形布阵进行前置布设,间距在200~300m时,防护效果最佳;在山体坡度较大情况下,若无法提前确定反辐射攻击方向,可以采用环形布阵,一旦发现反辐射武器,仅开启前方2个诱饵对反辐射武器进行诱偏.In order to solve the problem that traditional anti-radiation attack simulation model is difficult to evaluate protection effectiveness of radar decoys in complex terrain,this paper is based on the anti-radiation attack theory and complex terrain conditions to improve the traditional simulation model.According to the position relationship between the anti-radiation seeker and the decoy,the pitch angle of the signal is compared with the slope of the mountain in this direction,so as to judge whether the seeker and the decoy meet the intervisibility condition,to perfect the dynamic judgment conditions of the anti-radiation attack process,and to realize the analysis and evaluation of the protection effectiveness of radar decoy in complex terrain.The simulation results show that when the decoys are used to resist the anti-radiation missile attack in the complex terrain,the decoys prearranged with the rhomboid array,the protective effect is best with the distance between 200 and 300 m,and that in the case of a large mountain slope,if the direction of anti-radiation attack cannot be determined in advance,a circular array can be adopted,and only two decoys ahead are opened to lure them once anti-radiation weapons are found.
