红外场景辐射模拟技术发展

Development of Dynamic Infrared Scene Projection Technique

硬件闭环仿真系统是红外图像搜索制导系统、热像仪以及前视红外系统研制中的重要设备,红外场景辐射模拟器(红外投影仪)则是该设备中的核心器件,从辐射产生传输的角度,可主要将其分为4类:发射型、透射型、反射型以及激光型。介绍了各类型中典型模拟器的基本原理以及典型结构,并给出了部分关键性能参数(模拟温度动态范围、温度分辨率、空间分辨率、帧频)。

Hardware-in-the-loop （HWIL） simulation system is a key equipment used in developing the new generation of infrared imaging missile seekers, thermal imagers and forward-looking infrared systems, and the dynamic infrared scene projector （DIRSP） is the core device in HWIL. There are four kinds of DIRSPs （i.e. emissive, transmission, reflective and Laser） classified by the radiation and transmission manner of energy. The basic principle and typical architecture of DIRSP are introduced, and some key parameters （i.e. dynamic range, temperature resolution, spatial resolution, frame rate） are given.
