| 摘 要： | 在弹道修正弹药系统中,需要实时确定弹药的飞行姿态及方位信息.文中提出了一种基于磁探测技术和微机械陀螺技术的姿态测量方案,给出了利用地磁矢量和陀螺探测结果进行弹体姿态解算的数学模型.通过比较两种不同的数学处理方法分析得出,采用四元数法进行姿态解算,可以减少三角函数计算,提高运算速度和精度,且不会出现奇异现象.在Matlab环境下的仿真结果表明了该方法的可行性和有效性.

| Abstract: | In trajectory correction ammunition system,flight attitude and azimuth information of ammunition are needed to be determined in real-time.Therefore,an attitude measurement scheme which based on magnetic detecting and micro-mechanic gyro technologies was proposed.A mathematic model of attitude algorithm which uses geomagnetic vector and gyro detect result was established.By comparing the two different mathematical approaches,it is found that solve the posture solution by quaternion method can reduce calculat... |
