A system and method for detecting an aircraft jitter

摘要

Abstract The present invention relates to a system and method for detecting an aircraft jitter. The aircraft jitter detection system comprises: a jitter 5 detection apparatus, which detects accelerations of pitch and yaw of the aircraft; a data acquisition apparatus, which obtains accelerations in two directions detected by the jitter detection apparatus; and a jitter determination apparatus, which extracts frequency spectrum and energy information of the jitter according to the accelerations in two directions o obtained by the data acquisition apparatus, and determines whether the aircraft jitters.
