摘要
通过详细分析红外传感器对空中目标的成像过程,针对各个关键环节设计系统仿真流程,重点分析研究了飞机红外辐射特征和红外传感器成像原理。首先,运用红外物理学、空气动力学以及热传递等基本理论,结合飞机内部组成材料和结构特点,对蒙皮、尾喷管和尾焰等重点辐射区域建立仿真模型;在综合分析红外传感器组成结构和功能特点的基础上,对传感器光学系统和成像系统建立仿真模型;最后,飞机三维模型数据通过以上仿真模型处理,可实时生成飞机目标红外仿真图像。
After analyzing the course of Infrared（IR） sensor imaging for airborne target detailedly,this paper studies the infrared characteristic of plane and the theory of IR sensor mostly,besides designing the process of simulation system for every critical node.At first,by using the basic theory of infrared physics,aerodynamics,heat transfer and so on,the thesis presents several simulation models for the scarfskin,pout and plume of plane according to their radiant energy,with taking account into the inner materials and the configurable traits.On the base of synthesizing the structure and function of IR sensor,this paper establishes simulation models for IR sensor＇s receiving optics and imaging system.At last,the synthetic images of aircraft are generated in real time after all of these simulation models dealed with the three-dimensional data of the flight.
