摘要
通过建立海洋背景下的红外辐射模型,对机载红外探测系统所获得的热图进行了仿真计算,提出了一种从探测器红外焦平面上的探测像元到海面红外辐射单元的映射方法。利用MODTRAN软件计算了被探测海域各红外辐射单元通过大气传输后最终到达机载红外热像仪探测像元的红外辐射强度,最后利用Visual C++结合计算机图形学方法实现了红外热图的仿真计算。仿真结果基本反映了海面温度场的红外特性。
Based on the infrared radiation model established in ocean environment, the IR image obtained by airborne infrared detection system is simulated by computer. A mapping method from the survey element of detector focal plane to the sea level infrared radiation unit is proposed. After atmospheric transmission, each of the IR radiation unit in the detected sea area finally arrives at the detector unit of the airborne IR imaging system. And the infrared radiation intensity is calculated by MODTRAN software. The IR image is simulated by graphics and Visual C＋＋. The results can basically reflect the infrared characteristics of the sea surface temperature field.
