文中介绍了海洋作战环境下动态红外图像仿真的一种新思路。利用红外辐射的传播遵循几何光学传播原理的特性,通过对场景中红外辐射源的分析,将场景中各物体的几何模型、红外辐射在传播过程中的衰减和几何光学的方法相结合,建立了场号中等效辐射源模型。生成红外图像时,利用光线跟踪算法计算从等效辐射源发出的辐射经过场景中多次反射后最后到达成像面上辐射值,然后,利用物体的运动特性生成红外图像序列,形成仿真的动态红外图像。辐射传输过程中衰减的计算使用了LOWTRAN模型。 This paper introduces a new idea of ​​dynamic infrared image simulation in marine combat environment. The use of infrared radiation propagation follows the principle of geometric optics propagation. Through the analysis of the infrared radiation source in the scene, the geometrical model of each object in the scene, the attenuation of the infrared radiation in propagation and the geometrical optics are combined Field number equivalent radiation source model. When the infrared image is generated, the ray tracing algorithm is used to calculate the radiation reaching the imaging surface after multiple reflections from the equivalent radiation source and then using the motion characteristics of the object to generate the infrared image sequence to form a simulated dynamic infrared image. The LOWTRAN model was used for the calculation of attenuation during radiative transfer.
