| 摘 要： | 为实现对卫星平台力学环境的合理约束,研究了空间相机颤振与成像调制传递函数(MTF)下降的关系.通过理论分析,建立了基于统计矩的颤振传递函数的数学模型,实现了在特定函数振动和已知振动曲线情况下对MTF下降曲线的计算.针对某空间相机,利用MATLAB软件的图形用户接口(GUI)编制了颤振成像MTF计算软件,计算了在有随机噪...

| Abstract: | The relationship between the vibration of a space camera and its Modulate Transfer Function(MTF) degeneration is investigated.A suitable limitation for a satellite platform is developped through this research.Mathematical modeling of a vibrating MTF is calculated based on a vibration moment method.The MTF curve can be deduced from the vibration functions or curves.The vibrating MTF calculations uses Graphic User Interface(GUI) to develop an software for some space cameras.MTF values under sinusoidal vibrati... |
