摘　　要：本文重点研究相机口径、大气湍流强度和卫星轨高对高分辨率遥感卫星定位精度的影响。首先,基于Kolmogorov湍流理论建立对地观测大气湍流模型和湍流模拟方法;然后,仿真分析了相机口径、卫星轨道高度和大气相干长度对卫星定位精度的影响规律,推导出湍流波前倾斜与相机口径、卫星轨道高度和大气相干长度的普适公式;最后,基于该普适公式,得出卫星对地观测时抖动量的理论计算公式。本论文的研究可为后续高分辨率遥感卫星的设计、分析和评估提供大气湍流影响的理论依据。We focuse on the effects of camera aperture,atmospheric turbulence intensity and satellite orbit height on the tracking and positioning accuracy of high-resolution remote sensing satellites.Firstly,we establish a turbulence model and turbulence simulation method based on Kolmogorov turbulence theory for observation of the Earth.Then,the influence of camera aperture,satellite orbit height and atmospheric coherence length on the positioning accuracy of the satellite is simulated and analyzed,and then a universal formula is deduced to calculate the tilt aberration of turbulence wavefront.Finally,based on this universal formula,a theoretical formula for calculating jitter is derived for Earth observation.This work can provide a theoretical basis of the influence of atmospheric turbulence for the design,analysis and evaluation of high-resolution remote sensing satellites.
