This article presents a novel method to measure unbalanced moments in a two-axis gimbaled seeker commonly believed to seviously influence the tracking accuracy and stabilizing capability.This method enables individual measurement of unbalanced moments,and judgment of the seeker’s status-balanced or not.Furthermore,an instrument is designed based on this method and calibrated.The effectiveness of the proposed method is validated through a simulation.The experimental results show a satisfied level of accuracy the measurements have.This work forms a basis for the further development of a more stabilized gimbaled seeker with less induced vibration and consumed power.
