Abstract
The Infrared radiation characteristic research of high temperature target has an important role in the field of target recognition and tracking, etc. Affected by atmosphere, background environment and spatial resolution, the recognition to smaller thermal targets have certain limitations. This paper used two sensitive spectral intervals to high temperature object feature and used MODTRAN5.0 quantitative analyze infrared radiation energy of the heat target in the atmosphere into the pupil of the remote sensor. And this paper adopted the statistics method to analyze the sensitivity of the radiance results of the heterotherm and allohypsic targets under the condition of a very different enrage background. Simulation results compared with the results from Line by line integral model calculating HITRAN database using FASCODE model in the given same condition. The comparison results show the method in this article can be used fast and convenient to calculate high temperature target radiance and improve the recognition of high temperature target.
