Abstract: When building up the virtual battlefield system, to realize the three-dimensional (3D) detection range of radar in complex natural environment and complex environment of electronic interference, an improved support jamming model was proposed, according to the fundamental principle of Advanced Propagation Model (APM) and taking full consideration of the influence of electronic interference. This model mixed APM and electronic interference model together, and paid special attention to the refractive influence. Besides, this model could depict the double influence from complex natural and electronic interfering environments. Furthermore, a modified Marching Cube (MC) model, the triangles gained by MC being replaced by surface points and the interpolated points by middle points, was used to accelerate the process of visualization. According to the procedure of data gaining, data processing and data rendering, the 3D detection range of radar on specific electronic jamming environment was rendered via Visualization Toolkit (VTK).

摘要： 构建虚拟战场系统,为实现雷达在复杂自然环境和复杂电子干扰环境影响下的雷达探测范围,根据高级传播模型(APM)的基本原理,并综合考虑电子干扰环境的影响,提出了一个改进的支援式干扰模型。该模型混合了APM和电子干扰模型,重点考虑了大气折射率的影响,可描述复杂自然环境和复杂电子干扰环境的双重影响。在可视化时,利用点绘制代替面绘制和中点代替插值点改进了移动立方体(MC)方法,提高了渲染速度。根据数据获取、数据处理和数据渲染的流程,利用可视化软件包(VTK)实现了对雷达探测范围的三维显示。
