英文摘要	An angle-measuring error calibration method based on block three-order polynomial is proposed to reduce or eliminate the effects of machining error, assembly and adjustment error, sensor error on the angle-measuring accuracy of a laser seeker. With the consideration on the characteristics of each systematic error and the impact of random error during the experiment on calibration, the mapping relations between the pitch and yaw angles of the detector output and the real pitch and yaw angles of pointing vector are established through the block three-order polynomial for the calibration of angle-measuring error. The research results show that the calibrated means of yaw and pitch angle errors are decreased from 0.136 0 and 0.336 4 to 0.004 7 and 0.001 5, respectively, and the standard deviations of yaw angle error and pitch angles are reduced from 0.382 0 and 0.375 2 to 0.026 9 and 0.022 7, respectively. The proposed calibration algorithm has high accuracy and fine consistency in the field of view of seeker, and is easy to be used. A complicated mathematic model needs not to be established for parameter recognition when the proposed calibration method is used. Moreover, the method can be used for the error calibration of similar systems. 2019, Editorial Board of Acta Armamentarii. All right reserved.
