摘　　要：Micro-vibration is an important factor affecting the imaging quality and pointing accu-racy of the in-orbit satellites.To address the problem of micro-vibration compensation,a general summary for modeling,analysis,suppression,and compensation approach should be outlined.In this review,micro-vibration characteristics and its impacts on the payloads are firstly analyzed.Afterwards,methods for micro-vibration measurement are provided.In detail,the principles and practical applications of these methods are introduced.Then,advanced technologies for micro-vibration suppression are summarized from micro-vibration source attenuation,transfer path opti-mization and sensitive load isolation.Two approaches have been found to be effective for micro-vibration compensation.The one is the Line-of-Sight(LOS)stabilization assisted with Inertial Ref-erence Unit(IRU).The other is using image restoration technology to remove the blur caused by platform jitter.The compensation technique and research status of the two techniques are reviewed.This work will provide researchers with technical guidelines for micro-vibration suppression.
