加速度计/磁强计组合弹道测量方法
|
摘要
针对目前二维弹道修正组件弹道测量技术中卫星定位测量方式难抗干扰,惯导测量方式中陀螺抗过载低,不适用高转速、纯加速度计测量方式姿态测量误差大,有积累效应等问题,提出了利用多加速度计/磁强计组合的测量方法,利用加速度计测量弹丸位置、俯仰角和偏航角,利用磁强计测量滚转角。对该方法进行建模仿真,仿真结果表明,加速度计/磁强计组合弹道测量方法在不借助卫星定位的前提下能获得与有卫星测量系统同水平的精度,可满足二维弹道修正组件制导需求。
Aiming at problems in trajectory measurement technology including satellite positioning technology is liable to the influence of the jamming, gyro's low anti overload capability and high rotation speed inadaptability in INS, large error and error accumulation in accelerometer attitude measurement system, a measurement method using multiple accelerometers and magnetometers was proposed to measure projectile position, pitch angle and yaw angle with accelerometer, measuring roll angle with magnetometer. A simulation model was established,which showed that the system could achieve autonomous measurement and the accuracy met the navigation needs.
