摘　　要：为了便于现场实施时测量方法的选取,对目前的几种火炮回转半径间接测量方法进行了比较分析。从测量原理出发,分析各测量方法的误差源,采用蒙特卡洛方法对各误差源进行了模拟;比较了在不同方向射界下,各方法的测量均方差;分析了不受方向射界限制时,各测量因素对测量方法的影响。结果表明:在方向射界小于78°时,角度弦长法的测量均方差最小;在方向射界大于86°时,“五垂点”冗余测边网法的测量均方差最小。为火炮回转半径的现场实施和国家军用标准修订提供依据。To facilitate the selection of measurement methods in field implementation,several indirect measurement methods of gun rotation radius were compared.Firstly,the error sources of each measurement method were analyzed from the measurement principle,and the Monte Carlo method was used to simulate the error sources;secondly,the mean square deviation of each measurement method was compared under different direction shooting range;finally,the influence of each measurement factor on the measurement method was analyzed when it is not limited by the angle of traverse.The simulation results show that,the angle chord length method is optimum when the angle of traverse is less than 78°,meanwhile the five vertical points redundant trilateration method is the best when the angle of traverse is not less than 86°.It provides the basis for the field implementation of gun rotation radius and the revision of national military standards.
