雷达图像仿真是雷达系统模拟的一个重要方面，以数字地形为基础产生逼真的雷达图像，是雷达图像仿真的一个热点研究领域。探讨了一种基于软件化的以数字地形为基础的雷达图像仿真方案，通过在预处理阶段对数字地形格式和地形纹理进行转换，有效提高了运行时的数据加载速度和图像生成逼真度，并详细论述了模拟器的结构及软件的设计方法。仿真表明，该方法产生的图像逼真，实时性好，为工程实践提供了一种新的可行的雷达图像仿真方法。

Radar image simulation is an important part of radar system simulation,and the generation of high fidelity radar image based on digital terrain is a hotspot in radar image simulation research.A radar im-age simulating method based on software and digital terrain is described in this paper.Fidelity of image and speed of loading data are effectively improved by transformation of digital terrain format and terrain texture in the pre-processing stage.Structure of simulation and design of software are described in detail as well.Result shows that,this method can generate radar images of high fidelity with higher efficiency.It provides a new method of radar simulator designed for engineering.
