Abstract

This paper consults and improves the on hand computational methods and circuits, which comprehensively utilizes the knowledge of the Aerodynamics, the heat transfer theory, the radio optics, ANSYS and so on. In the analysis of the IR characteristics of aerial targets, taking it into account that most of the computing methods on hand are empirical or semi-empirical, which are more simple, but more limited, less sufficient and scientific and have more human factors, so we begin with the determination of the thermal field, adopt the numerical method to realize the calculation and modeling of the IR radiation with ANSYS, analysis how the spectral coverage and the observed bearing affect the IR radiation, and then get the credible and all-side numerical calculation results. Then, this paper introduces a method utilizing 3DS MAX and OpenGL to generate the IR picture of the target, which divides the grey level of the IR radiation reasonably according to the final numeric calculating results and the principle of the grey level division, and then we generate the IR pictures of the aerial targets.
