摘　　要：为提高激光导引头测角精度,研究了激光导引头测角误差的来源,并分析了直写式激光导引头标定系统误差。首先,分析了激光导引头内光学系统和探测器安装误差对导引头测角的影响;其次,介绍直写式激光导引头标定系统的工作原理,给出理想条件下转台转角和导引头测角关系;再次,为了提高标定后导引头测角精度,分析了标定系统存在的安装误差;最后,针对一次实际的标定过程,结合文中分析方法对标定系统误差进行了校正,导引头零位误差由校正前的2.5 mrad降低到了1 mrad以内。文中结论为直写式激光导引头标定系统中的结构安装精度要求提供了分析方法,进而提高了标定后激光导引头的测角精度。In order to improve the angle measurement accuracy of laser seeker,the source of angle measurement error of laser seeker was studied,and the error of direct writing laser seeker calibration system was analyzed.Firstly,the influence of the optical system in the laser seeker and the detector installation error on the angle of the seeker was analyzed.The relationship between the angle of turntable and the angle of seeker under idea conditions was given.Secondly,the working principle of the direct writing laser seeker calibration system was introduced.Thirdly,in order to improve the angle accuracy of the calibrated seeker,the installation error of the calibration system was analyzed.Finally,according the analysis method in this paper,the calibration system error was corrected,and the seeker zero error was reduced to within 1 mrad from 2.5 mrad before the calibration.The conclusions of this paper provides an analytical method for the precision requirement of the structure installation in the direct writing laser seeker calibration system,and thus improves the angular measurement accuracy of the laser seeker after calibration.
