摘要

针对圆型目标模拟器模拟来袭飞机或导弹等红外三角形目标逼真模拟问题，研究了动态红外三角形模拟技术。采用等腰三角形的几何原理，提出一种新型大小和方向连续可变而质心不变的等腰三角形光阑设计方法，实现了0°~3°大小、0°~360°方向动态可调的三角形目标；采用红外宽光谱偏振器组合技术，实现了目标源或干扰源的辐射强度0~100%的连续变化；采用二维平移台及可变圆形光阑，实现了干扰的大小变化及其轨迹变化；研究了基于Windows操作系统的实时控制技术，设计了包括MFC和RTSS双进程的主控软件，实现了控制指令500 μs的实时响应。试验结果表明，带有干扰源的动态红外三角形模拟器能逼真模拟来袭飞机或导弹及释放诱饵的红外辐射特性变化过程。

Abstract

Aiming at the fidelity problem of circular target simulator for simulating the infrared triangle targets such as airplane, missile and so on, a simulation technique of dynamic infrared triangle was studied. Using isosceles triangle geometrical principles ,a novel design method was proposed for isosceles triangle aperture whose size and direction were variable serially and centroid was invariable, and the dynamic triangle target with the size of 0°~3°and direction of 0°~360°was achieved. The radiation intensity from 0 to 100% for target or decoy was continuously changed by adopting a combination technique for infrared polarizer with wide spectrum. The decoy′s size and location were variable by using two-dimensional mobile platform and changeable circular aperture. The real-time control technology on Windows operating system was studied, and the main control software including Microsoft foundation class (MFC) process and real-time sub-system (RTSS) process was designed, satisfying the 500 μs real-time response of control instruction. The result shows that the dynamic infrared triangle target simulator with a circular decoy can accurately simulate the infrared radiation changing process for attacking airplane or missile and releasing decoy.
