摘　　要：为了提高低空突防中雷达探测盲区预测的可靠性,提出了一种雷达探测盲区预测方法。该方法在分析雷达探测性能的基础上,基于数字地图抽取地形剖面,采用抛物方程法计算电波在空间的传播损耗,根据雷达探测门限预测某高度平面上的雷达探测盲区。仿真结果表明,该方法能够有效预测复杂环境下的雷达探测盲区,提高飞行器低空突防的成功概率。A new method of radar blind space prediction is proposed to improve the reliability of calculation results for low-altitude stealthy penetration.Based on analysis of radar detection performance,the terrain profiles are extracted from digital maps,and wave propagation loss is calculated using parabolic equation method.Then the radar detection blind space for a specific height is predic-ted according to the radar detection limit. Simulation results show that this method can effectively predict the radar blind space in complex environments to enhance the probability of success for low-altitude stealthy penetration.
