海洋背景下运动目标的天基红外探测场景生成系统
A space-based infrared detection scene generation system for moving objects with sea background
摘要
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.关键词
