基于现代战争对导弹的要求,需要提升导弹的打击密度以及打击精确度,从而提高导弹的杀伤力。由于地磁场的作用,弹体空中姿态受到影响,利用磁阻传感器对空中弹体的姿态进行测量,运用四元数法建立弹体空中姿态数学模型,利用Matlab对弹体空中姿态进行仿真。通过仿真,计算出弹体空中的理想姿态,从而对弹道进行修正,将大大提升导弹的打击密度及精度,从而实现现代战争的技术要求。

To meet the requirement for missile by modern warfare, the missile's strike density as well as the precision should be improved for missile's lethality improvement. Due to geomagnetic field, the projectile's posture in the air was affected, the aerial projectile's posture was measured with magnetic resistance sensor, the mathematical model of the projectile's posture in the air was established by the quaternion method, and Matlab was used for the simulation of the projectile's posture in the air. Through simulation, the ideal posture of the projectile in the air was calculated, thus the ballistic was corrected, and it would improve the missile's strike density as well as the precision greatly so as to meet the technical requirements by modern war.
