摘　　要：车体扰动是行进间射击最主要的误差源,直接影响着自行高炮的射击精度。通过对某自行高炮的动飞试验数据进行计算、分析,寻求车体姿态扰动对射击诸元造成的影响。在实际计算中,以处理后的经纬仪测量结果作为目标航迹真值,以自行高炮CAN总线录取火控输出数据作为被测值,取差计算火控输出诸元误差,同时,实时采集行进中的车体姿态角,用MATLAB对车体姿态角(及其变化率)和火控射击诸元误差进行计算分析,研究得到了两者之间的函数曲线。该计算结果可为自行高炮的总体设计和部件设计提供参考。Hull attitude disturbance is the main error source of fire during marching,it has direct influence on fire accuracy of the self-propelled anti-aircraft（SPAA）gun.Calculation and analysis were carried out on dynamic flying data of a SPAA gun in development so as to search the effect of hull disturbance on fire data error.In practical calculation,the worked theodolite measuring value was regarded as target flight true value and CAN bus extraction value of the SPAA gun was regarded as measured value,the margin between the two values was obtained to calculate fire control data error,at the same time,hull attitude angles in traveling were collected in real time.The calculation and analysis were carried out on the hull attitude angle（and its change rate）and fire control data error by use of MATLAB,and the function curve between the hull attitude angle and fire control data error was acquired.The calculation results can provide reference for overall and part designs of SPAA gun system.
