| 摘 要： | 平均后向散射系数的计算是地杂波仿真中的重要内容。详细论述了将数字高程模型（digital elevation model,DEM）数据用于获得后向散射系数图的方法。DEM数据经过单元划分和地形遮蔽处理,可判断各单元是否被遮蔽,结合雷达天线方向图,可知道哪些单元是雷达天线可视的。利用现有的平均后向散射系数模型,通过计算获得每个可视单元的平均后向散射系数。仿真结果表明：将DEM数据用于地杂波仿真是可行的。 |

| Abstract: | Calculation of average backscatter coefficient is an important part of the simulation of land clutter.In this article,the approach to get land clutter map which applied digital elevation model(DEM) data is introduced in detail.We could know whether radar cell was masked after transforming DEM data into the radar coordinate system and terrain masking processing,and which units were visible combining radar antenna pattern.Using the existing backscattering coefficient models,we could get average backscattering... |
