飞机红外辐射图像仿真研究

为研制火控雷达红外子系统训练模拟器,必须对飞机的红外辐射现象进行仿真研究,创建飞机与雷达的对抗环境,从而实现对抗训练.文章阐述了红外仿真的思想,采用3DSMax软件对飞机几何建模,以飞机典型部位的红外辐射特征为对象,通过输入飞机及大气的相关参数,对飞机的零视距离红外辐射出射度、大气透射率以及灰度值进行计算;以面向对象技术设计了仿真对象、类和人机接口,编程生成了飞机的红外仿真图像;通过对飞机三维可见光模型和典型频段的红外仿真图像进行分析,结果表明飞机红外辐射仿真图像能够满足某火控雷达训练模拟器研制的需要,对装备训练模拟器开发有一定参考价值.

Simulation of Infrared Radiation Image of Airplane

For researching the training simulator of the infrared subsystem of fire control radar,it is necessary to research the simulation of infrared radiation of airplane.With creating the counter-condition of airplane and radar,the countertraining would be carried out.The article expatiates the idea of infrared simulation.The geometric model of the airplane is created by using the 3DSMax software.Taking the characteristics of infrared radiation of the typical parts of airplane as the object,by inputting correlative parameters of airplane and atmosphere,it will be calculated that the emittance of infrared radiation in zero-horizon distance,the efficiency of atmosphere transmission,and the gray-value of every part.Based on analyzing the 3DS model of the visible light of airplane and the infrared simulation image of typical frequency,the results indicate that the simulation image of infrared radiation of airplane would satisfy the need of researching the fire control radar training-simulator.This would be referenctial to the development of other arming training-simulator.
