摘要：

海天背景红外热像的理论建模对于研究舰船目标的红外热像理论模型是相当重要的。该文重点研究了3-5微米波段海面红外热像的理论模拟方法。使用了国际标准的 JONSWAP 模型，并且利用快速傅立叶变换方法来模拟海面的粗糙程度。同时，充分考虑了太阳、天空等各个环境参数，利用计算机数值计算方法理论模拟了海面3-5饿波段红外热像，并研究了探测器的仰角对热像的影响。

Abstract: The theoretical modeling of the infrared images of sea surface is quite important to the research of the infrared images of the ship.The paper studies the method of simulating the infrared images of sea surface in the wave band of 3-5 micron. The coarseness of sea surface is calculated by making use of the JONSWAP model and FFT.Fully considering various enviromental parameters such as sky radiance and sun radiance,the infrared images of sea surface in wave band of 3-5 micron can be simulated on computer.Also the paper has studied the influence of the angle of the detector.
