摘要

为了研究海面的红外辐射特性,提出了基于二维反射率的粗糙海面红外辐射计算方法。综合考虑海面红外辐射的各个因素,建立了海面的红外辐射模型,全面考虑风速、风向、遮蔽效应等各种影响,推导出粗糙海面的二维反射率计算方法,并进而计算出海面的红外辐射亮度。利用该计算方法,有效计算了中波和长波海面的红外辐射亮度,相比于经验公式计算方法,计算结果与实测数据有较好的一致性,该计算模型可以为海面背景的红外特性分析、探测及仿真提供参考数据。

Abstract

To study the infrared characteristic of sea surface, a method of calculating infrared radiation of sea surface was proposed. The infrared model of sea surface was constructed after each infrared radiative component had been studied. Considering wind speed and wind direction, a method of computing infrared reflectance of sea surface was deduced, and reflectivity and emissivity of sea surface were obtained. Radiance of sea surface was computed in middle wavelength and long wavelength with this method. The result shows that actual measurements and data from the model are consistent; hence the method of calculating infrared radiation of sea surface is applicable as the data source in the infrared characteristic analysis, detection and simulation for the ocean background.

Key words： sea surface; infrared radiation; Cox-Munk model
