研究了从Globe地图中任意抽取电波传播路径地形剖面的方法,并应用抛物方程模型计算了雷达波在任意地形上的传播损耗,在此基础上计算出单站雷达对特定目标高度的全方位探测范围,克服了目前几何光学法由于不能实现对复杂地形的准确建模而导致计算结果可靠度不高的缺点,为有效预测雷达探测的覆盖区和盲区提供了一条新途径.

In this paper the method of extracting terrain profiles arbitrarily from the Globe maps for the radio wave propagation path is studied.The radar wave propagation losses on arbitrary terrain are also computed using the parabolic equation model.Based on the computation,the monostatic radar omnidirectional survey range for a specific target height is calculated.The method overcomes the shortcoming of geometrical optical method which can't give accurate terrain modeling and leads to uncertain calculation result.In this paper a new approach to predicting the radar coverage and blind area effectively is proposed.
