摘　　要：目标成像技术一直是雷达图像仿真领域研究的热点问题,基于三维实体模型实现目标成像的模拟为雷达图像仿真提供了一种新方法。在对三维实体模型在雷达图像仿真中的应用特点进行深入分析的基础上,综合考虑雷达成像的影响因素,结合SEDRIS思想,提出了一种基于网格化的三维实体模型表示方法,深入分析了模型组成要素、组织结构与调度方法等,三维模型SAR成像仿真实验证明了该方法的有效性和实用性。Object imaging is an important aspect of radar image simulation. We proposed a new method to simulate the radar image based on 3D entity modeling. Primary data format of 3D entity modeling and the features of radar image were analyzed thoroughly. To improve the effect of 3D entity modeling in simulation,a new data organization structure of 3D entity modeling was designed to apply the radar image simulation combined with SEDRIS to discuss model elements,the structure of the organization and scheduling methods thoroughly,with the method of gridding saving. The experiment of SAR image simulation proves that the method can satisfy the radar image simulation.
