现有红外仿真软件处进行人造水雾图像仿真时，均无法体现出水雾的扩散特性，使仿真图像真实度较低。针对这一问题，基于高斯扩散模型与M IE散射理论，将水雾空间划分为多个子空间，通过计算不同子空间内的水雾特性参数，建立一种新型水雾仿真模型。根据所建模型，利用M atlab编程得到的仿真图像与现有软件仿真结果相比，图像真实程度有很大提高。
現有紅外倣真軟件處進行人造水霧圖像倣真時，均無法體現齣水霧的擴散特性，使倣真圖像真實度較低。針對這一問題，基于高斯擴散模型與M IE散射理論，將水霧空間劃分為多箇子空間，通過計算不同子空間內的水霧特性參數，建立一種新型水霧倣真模型。根據所建模型，利用M atlab編程得到的倣真圖像與現有軟件倣真結果相比，圖像真實程度有很大提高。

The simulation image could not display the scattering of water mist using the existing infrared simulation software, which makes the image unreliable. In order to solve this problem, the water mist space is divided into multi‐subspace. A new type of water simulation model is established using the calculation of water mist of different subspace parameters, based on Gaussian diffu‐sion model and MIE scattering theory. According to the new model, simulation image through Matlab is compared with existing soft‐ware simulation results to show that reliability of the infrared image has been greatly improved.
