摘　　要：模拟舰船与海面红外热像可以直观定性地分析舰船目标与海面背景的对比特征，判别舰船目标识别的特征部位，具有强烈的实际军事需求和应用背景。本文首先根据坐标变换及投影法并结合大气传输模型编写程序模拟了8-12μm波段舰船的红外热像。可以看出烟囱出口是舰船探测最主要的识别部位。然后使用Cox-Munk粗糙海面模型和遮蔽函数并结合蒙特卡洛方法编写程序模拟不同风速条件下海面的红外热像，得到海面平均辐射亮度随风速增大而减小的结论。最后将舰船目标与海面背景的红外图像进行融合，分析不同探测距离条件下海面背景下舰船目标的红外热像特征，计算结果表明，随着探测距离的增大，舰船整体辐射亮度减小。The simulation of ship between ship targets and sea bac and sea kground infrared thermal imaging can visually compare the characteristics , it also can recognize the feature parts of ship and be the key is- sues because of the strong background and actual military needs and applications. This paper simulates the 8 - 12 μm wavelength infrared thermal image of ship according to the coordinate transformation and projection method combined with atmospheric transport model programming, as a result the ship chimney outlet is the most important recognition site. Then use the Cox - Munk rough sea surface model and mask- ing function combined Monte Carlo Simulation prepared under different wind conditions of the sea surface infrared image, obtained conclusions that an average sea surface radiance decreases with the wind speed increase. Finally, fuse the ship target with sea background infrared image, analysis of infrared thermal imaging characteristics under different conditions detection range sea background ship targets, the results show that with the increase of the detection range the ship radiance radiance decreases
