摘要

围绕海洋背景下飞机和海面舰船等运动目标的探测需求，本文研究了目标和载荷在多个坐标系下的空间位置与运动特性，建立了天基探测场景的几何模型；通过Pierson-Moskowitz海洋谱模型计算海面起伏，实现大气层外海面辐射亮度的建模仿真；利用多种目标的三维几何模型，实现目标辐射特性的建模仿真。在上述研究的基础上，利用MATLAB平台，开发了一套海洋背景下多种运动目标的天基红外探测场景生成系统。结果表明：该系统生成的海洋辐射亮度均值在中波红外谱段优于Modtran的生成结果，在长波红外谱段与Modtran的生成结果之差小于3%。该系统可生成连续的海面背景下运动目标的辐射亮度图像，为开发天基红外探测系统提供技术支撑。

Abstract

Revolving around the detection requirements for moving targets such as aircraft and sea surface ships under the sea background

a research was conducted in space position and motion characteristics of the target and load

thus a space-based detection scene model was established; then

the sea surface fluctuation was calculated through the Pierson-Moskowitz model to achieve modeling and simulation of sea radiance outside the atmospheric layer; finally

three-dimensional geometrical model of multiple targets was used to realize modeling and simulation for radiation performance of the target. Based on the above-mentioned researches

a space-based infrared detection scene generation system was developed by virtue of the MATLAB platform. The experiment indicates that sea radiance mean produced from such system is superior to that produced from Modtran in the section of medium-wave infrared spectrum; while in the section of long-wave infrared spectrum

it is 3% lower than that produced from Modtran. This proposed system

which is able to generate continuous radiance images of the moving target under sea background

provides a technical support for the space-based infrared detection system.
