卫星平台震颤是卫星受到内外部因素影响引发的一种幅值较小的颤振响应。随着空间分辨率的提高,平台震颤成为影响高分辨率卫星影像高精度处理与应用的关键因素。首先对遥感卫星影像平台震颤分析与处理的国内外现状进行了概述,然后总结了高分辨率光学卫星平台震颤地面处理框架,对震颤姿态确定、震颤误差检测与建模以及震颤畸变校正3个关键技术进行了阐述,最后对未来超高分辨率光学卫星平台震颤分析与处理的发展方向进行了展望。

Satellite platform jitter is a flutter response caused by the internal and external factors during the flight. With the improvement of spatial resolution, platform jitter has become the key factor in high resolution satellite image high-accuracy processing. In this paper, the current situation of remote sensing satellite image platform jitter analysis and processing is firstly summarized. The ground jitter processing framework for high resolution optical satellite is further presented, and the key techniques of jitter attitude determination, jitter error detection and modeling, and correction of jitter distortion are expounded. Finally, jitter analysis and processing for ultra-high-resolution optical satellite in the future is prospected.
