针对弹道修正弹的修正控制过程中最关键的弹丸滚转角的解算问题，采用GPS/MR组合对弹道修正弹数据进行处理。基于卫星和地磁组合的弹道修正弹滚转角测量原理，建立滚转角的数学解算模型。通过拉格朗日插值法对数据进行插值处理，利用高频率的地磁数据进行小段的正弦拟合得到正弦函数角速率，代替滚转角的角速度从而求得滚转角，并以Matlab进行仿真比较。仿真结果表明：通过高频率的地磁数据进行插值处理的方法是可行的，能满足实际工程需求。

In the trajectory correction projectile revision control process, we need to know the real-time angle of the projectile accurately. The roll angle is the most important. In this paper, established the mathematics model on the basis of measurement principle of roll angle of trajectory correction projectile based on GPS and magnetic resistance(MR). The data was interpolated by Lagrange interpolation and sine fit the high frequency geomagnetic data into small pieces to solve the angular rate to replace the angular velocity of the roll angle so as to obtain the roll angle. Then simulation and compare it through Matlab. Result shows that the interpolation method through the high-frequency geomagnetism data is feasible, and meets practical demand.
