一种可扩展的红外场景仿真系统设计与实现

Design and Realization of an Extensible Infrared Scene Simulation System

红外场景仿真对于科研现代化具有重要意义。一个良好的红外场景仿真系统应该扩展性好,支持多种目标平台如飞行目标、地面目标、海面目标等;同时仿真模式多样,支持温度场在线、离线计算,支持各种参数的输入;而且应能够方便地移植到多种操作平台如PC机或专用硬件板卡上。以上三点对国内现有研究提出了更高的要求。本文描述了一种可扩展、多模式、平台独立的红外场景仿真系统。该系统合理设计了参数接口,使得各种类型的目标以及目标的不同模块均能得到合适的处理;支持温度场在线迭代计算,以及离线预计算;同时采用标准C语言独立编写了三维渲染引擎,而不是借助于DirectX,OpenGL等商用引擎,使得系统本身可方便移植到各类平台如DSP板上;并给出了该系统的部分仿真结果。

Infrared scene simulation plays an important role in the modernization of scientific research. A welldesigned infrared scene simulation system should be extensible, which means it should support multi-type targets such as aero crafts, targets on the land or in the sea. It should also support multiple modes of simulation, and support the temperature field to be calculated on-line or off-line. It should also be easy to transplant onto different platforms such as PCs and special circuits. The three points above bring forward a higher request to the domestic researchers. An extensible, multi-modes, platform-independent infrared scene simulation system is described. This system carefully designed the parameter interfaces, which make different kinds of targets and different modules of a target be properly treated. It also supports the on-line and off-line iterative calculation of temperature field. At the same time, its three dimensional rendering engine is independently coded by standard C instead of commercial engines such as DirectX or OpenGL, which allows the system easily transplantable. At last the simulation result is showed.
