摘　　要：针对滚转弹需要实时滚转信息进行指令控制,传统滚转角测量方法标定复杂且难以实时有效获取的难题,提出利用双轴标量地磁信息进行滚转信息解算。在研究滚转弹运动特性的基础上,确定滚转弹滚转信息解算坐标系;对固连弹体的双轴地磁传感器输出的标量地磁信息进行数据min-max标准化,归一与零位消除,并搭建半实物算法仿真平台。经仿真与实验结果验证,所提方法能够真实反映滚转弹飞行过程的滚转变化,响应快、误差小,且满足对滚转弹实时指令控制需要。As the rolling missile needs the real⁃time rolling information to perform the instruction control,but the traditional rolling angle measurement method has complex calibration and is difficult to get it effectively in real time,the rolling information calculation utilizing the biaxial scaled geomagnetic information is proposed.On the basis of studying the motion features of the rolling missile,the rolling information of the rolling missile is determined to calculate the coordinate systems.The data min⁃max standardization,normalization and null elimination of the scalar geomagnetic information outputted by the biaxial geomagnetic sensor of the fixed missile body are conducted,and the simulation platform of semi⁃physical algorithm is built.The results of simulation and experiment resurts verification show that the proposed method can truly reflect the rolling change of the rolling missile during its flight process,has fast response and small error,and can meet the needs of real⁃time instruction control of the rolling missile.
