| 摘 要： | 建立了航用弹道修正弹滚转角辨识系统数学模型，利用向弹上引信装定的初始信息及磁阻传感器探测到的地磁信息，使用滚转角解算算法求出滚转角。对理想弹道条件下的误差进行分析并通过实例进行仿真，验证该滚转角辨识系统可有效辨识出弹体滚转角，在给定条件下能达到较高精度，误差基本在弹丸实际使用的允许范围之内。

| Abstract: | A rotation angle identification model of trajectory correction projectiles is constructed. By using the initial data set to the fuze and the geomagnetism information detected by the magnetic sensor , the rotation angle is calculated through the rotation angle identification algorithm. The errors based on ideal trajectory are analyzed and emulation about an example is performed. The analysis and emulation indicate that the ratation angle identification system can effectivelly identify projectile rotation angle and the precision is higher on ideal condition, errors are in allowable range. |
