摘要:
针对导航和姿态测量中地磁场三轴分量方法无法得到全部姿态角信息的问题,该文分析了基于两非正交磁传感器的极值比解算姿态角方法的假设条件和测量原理。利用误差分配理论和数值仿真技术,结合弹丸实际运动规律和我国地域特征,讨论了该方法所测姿态角的理论误差范围及测量盲区,探讨了该弹体定姿方案的适用性。结果表明,该方法在[15毅,75毅]射角时测量误差在依1毅内,且满足普遍旋转弹体的姿态测试要求。半实物实验验证了该方案的有效性。
Abstract:
In view of that the three-axis components method of the magnetic fields can not give thewhole information about the attitude angle in the navigation and the attitude measurement, theassumptions and the measurement principle of the extremum ratio solver algorithms of the attitudeangle are analyzed based on the two-non-orthogonal magnetic sensors. Combining the actual movementof the projectile and the regional characteristics in China,the measurement error range of the attitudeangle and the blind spots are studied using the error distribution theory and numerical simulation,andthe applicability of the missile body attitude measurement method is discussed. The results indicatethat the error of attitude angles can be kept within ±1°with the[15°,75°]fire angle,and the methodmeets attitude test requirements of the common rotary projectiles. The effectiveness of the measurementprogram is verified by the semi-physical experiments.
