This method is used to distribute and analyze the accuracy of themast鄄mountedphotodetection system. Theoverall accuracy index isseparately distrib鄄 uted tophotodetection systemandmastplatform system. Thisaccuracy distributioniscalculatedbasedon the systemparameterstoprovewhether it could satisfy the accuracy requirement. Therationality of accu鄄 racy distribution approach of the mast鄄mounted photodetection system is validated through infield experi鄄 ment. The calculated and experiment error values of azimuth direction of the photodetection system are 1郾2义 and 1郾9义,respectively,which are less than2义. The calculated and experiment error values of azi鄄 muth directionof themastplatform systemare 19郾7义and23郾5义,which are
