| 摘 要： | 针对以往三轴磁传感器和加速度计组合测量高转速弹体姿态的不足，提出了一种新的姿态测量方案。该方案由两个磁传感器和两个加速度计以特定的方式安装及相应的解算方法组成。说明了传感器的布阵方式，并给出了弹体姿态解算的数学模型和解算方法。该解算方法包括Magsonde Window和最值之比的证明以及姿态角解算的理论分析，最后对此方案进行了建模与仿真。仿真结果表明，解算的姿态角与真实姿态角相符。

| Abstract: | In allusion to the limitations of the traditional attitude measurement system consisting of a three-axismagnetic sensor and two accelerometers on high-spinning projectile,a new scheme comprised of two magneticsensors and two accelerometers installed in a particular way is given.The configuration of the sensors is de-scribed.The calculation method and the mathematical model of the projectile attitude based on the sensor configu-ration are discussed.The basic calculation method including the Magsonde Window,the proof of the ratios ofmaximums and minimums and the calculation of the attitude angles are analyzed in theory.Finally,the system issimulated under the given conditions.The simulation result indicates that the estimated attitude angles are inagreement with the true attitude angles. |
