通过分析镜像干扰机理,建立数学模型,并分析擦地角与地面反射系数的关系,确定布鲁斯特角。在此基础上,设计超低空高抛弹道、镜像干扰的判别准则以及镜像干扰时的控制指令灰色预测,仿真和实际飞行试验结果表明,超低空高拋弹道在弹道的后段接近或达到布鲁斯特角时,能较好的避开镜像干扰,而在弹道的前段采用判别并补偿的方法能较好的抑制镜像干扰,从而扩大了杀伤区的近界。

By analyzing the mirror interference principle and builds the mathematical model, and analyzes the relation between grazing angle and earth reflective factor, establishing the Brewster angle. Herein, we design the super low level high-parabolic trajectory and the discrimination criterion of mirror interference, and the control instruction gray prediction with mirror interference. The simulation and actual flight test results show that the super low level high-parabolic trajectory can avoid the mirror interference when it is close to or reach the Brewster angle at the initial stage of trajectory, and the mirror interference will be suppressed and consequently the expand the short extent of killing zone at the end of trajectory.
