遥感卫星全视场成像质量仿真方法研究

基于卫星工具包(STK)和MATLAB软件,提出了一种对卫星全视场成像进行物理建模分析的交互仿真方法。以一颗运行在650km高度的太阳同步轨道、具有侧摆能力的遥感卫星为例,对相机在运动中的全视场积分时间偏差和全视场偏流角修正残差进行了仿真分析。仿真结果表明,文章提出的方法能够较精确地对相机在轨全视场的成像质量进行分析,从而可用于在轨成像性能预估。该仿真方法还能以卫星工程数据作为输入,用于卫星星上算法验证、在轨误差分析补偿等方面,为保障卫星在轨成像质量发挥作用。

Simulation Method Analysis on Full-view Imaging Quality for Remote Sensing Satellite

An interactive simulation method based on STK and MATLAB is proposed to imple- ment the full-view physical modeling and analysis. And a 650km sun-synchronous orbit remote sensing satellite with rolling maneuver ability is taken as an example for the full-view analysis in terms of integration time error and drift angle correction residual error. The simulation results show that this method can be used to analyze the full-view imaging quality in a precise way and estimate in-orbit imaging quality. This simulation method can use satellite engineering data as input, and be used in analytical model verification and in-orbit error analysis and compensation, and provide support for imagery quality assurance.
