建模和仿真在包括导弹系统在内的宇航系统中的作用逐步提高,并将在今后二十年起到更加重要的作用。由于计算处理能力将提高几个数量级,计算和数据存储成本将进一步降低,且具有余量。仿真越来越复杂的物理过程的能力将变得更加受仿真所涉及子模型的拟真度的限制,而非受仿真所能得到的计算能力的充足性的限制。文中概述了建模和仿真技术在红外成像制导系统全寿命周期开发和试验评估中的作用,介绍了基于GPU实时红外场景计算机硬件技术、实时红外场景生成算法与软件、多光谱实时图像合成技术等实时红外场景生成技术的研究进展,概述了实时红外场景生成技术在红外成像制导系统开发与试验评估中的应用。
The role of modeling and simulation in aerospace systems, including missile systems, is gradually improving and will play an even more important role over the next two decades. As computational processing power will increase by several orders of magnitude, computational and data storage costs will be further reduced with margin. The ability to simulate more and more complex physical processes will be more limited by the fidelity of the sub-models involved in the simulation than by the adequacy of the computational power available to the simulation. This paper summarizes the role of modeling and simulation technology in the development and test evaluation of the whole life cycle of infrared imaging guidance system, introduces the hardware and software of real-time infrared scene based on GPU, real-time infrared scene generation algorithm and software, multispectral real-time image synthesis and so on The research progress of real-time infrared scene generation technology is summarized. The application of real-time infrared scene generation technology in the development and experimental evaluation of infrared imaging guidance system is summarized.
