摘　　要：提出一种天基观测空间目标可见光图像仿真方法,观测平台及目标的运行速度和空间位置信息由卫星工具包(STK)生成,成像过程由Matlab编程实现。该方法的优越性在于利用STK的可视化功能,控制观测平台和目标的轨道参数,使目标能够进入观测相机的视场,而Matlab具有强大的图像处理函数库,在序列图像生成过程中,可方便地对图像添加各类噪声和效应,使图像更加真实;生成的仿真图像主要用于空间目标检测算法的研究。最后分析了仿真图像中空间目标和恒星的运动性质,为完善空间目标检测算法的性能提供了依据。A visible light image simulation method for space-based observation of space target is presented. The speed and position information of the observation platform and the target is generated by the STK,and the imaging process is implemented by Matlab programming.The superiority of this method is to use the visual function of STK,and the orbital parameters of the observation platform and target can be controlled to make the target enter the FOV of camera.Matlab has a powerful image processing library,which can add all kinds of noises and effects to the image during sequence image generation to make the image more realistic. The generated simulation images are mainly used for research on space target detection algorithm.Finally, the motion properties of space target and the stars in simulation image are analyzed,which provides a basis for improving the performance of space target detection algorithm.
