中文摘要:弱小目标检测是当今研究的热点问题之一。分析目标背景红外特性,进行红外仿真可作为弱小目标检测算法的研究基础并为目标检测算法研究构造仿真平台。本文在建立弱小目标热模型的基础上,考虑了海面背景的辐射模型以及红外辐射的大气吸收模型,进而计算弱小目标的红外辐射及大气衰减量,最终可获得经过大气衰减的弱小目标红外仿真图像,取得了较好的效果。

Research on infrared radiation characteristics of the small target in the complexity of the marine environment and image simulation
Abstract:Small target detection is a hot issue in today's research.Based on the infrared analysis of the background and the target characteristics,the infrared simulation can be used as small target detection research base,and also as the target detection simulation platform structure.Based on the thermal model of a small target ,the sea background surface radiation model and the atmospheric propagation model of infrared radiation is discussed in this paper. Then, the infrared radiation , the atmospheric transmission rate of a small target is calculated. In the end , the infrared image simulation of a small target including atmosphere transmission is obtained, and it achieves good result.
keywords:small target,sea background,infrared radiation,infrared image simulation
