摘　　要：由于应用需求的驱使,红外成像仿真技术越来越受到国际社会的关注,并已成为现代国防科技的关键技术之一。针对深空背景条件下的锥形目标,可利用结点热网络法求解其表面温度分布,然后计算目标与背景的红外辐射,再将探测器接收的辐射照度转化为灰度,并加入探测器自身效应的影响,就可仿真得到锥形目标不同成像状态的图像。此方法完整地实现了空间锥形目标在红外探测器上的成像过程,同时考虑了多种因素的影响,具有很高的真实性与逼真度,可为红外成像系统的研制及目标检测识别算法提供测试场景与依据。According to the application requirements,infrared imaging simulation is attracting more and more attention all over the world as a kind of key national defense technology at present.For the taper target in the space,the distribution of its surface temperature can be calculated by node thermal network,the infrared radiation of the target and background can be then deduced,after transferring infrared irradiance received by the detector into grayscale and adding the inherent effects of the detector,the infrared images of taper target in different states from the deep space can be simulated.This method realized the whole imaging process of the space target with the infrared detector.As more factors were taken into account in this paper,infrared images of a higher degree of authenticity and reality would be simulated,which can be used as test scenarios or provide a basis for the infrared imaging system or the algorithm of target detecting and recognition.
