摘要
为提高制导枪榴弹的命中率,要求弹载测姿系统实时地输出并存储精确的飞行参数.在枪榴弹空间狭小过载偏高环境下,姿态测试系统存在的误差很难通过庞大的硬件电路减小,针对这个问题采用了在试验前校准的方法,即对惯性测量单元标定的同时将采集模块采集测量的结果修正到与实际信号尽量贴合.实验数据分析结果表明,经过校准的系统采集的载体姿态数据精度提升了1~2个数量级.通过实验证明了该方法在理论层面有效可行.
In order to improve the hit rate of the guidance gun grenade,the missile-borne attitude measurement system is required to output and store accurate flight parameters in real time.In the narrow and overload environment of the gun grenade space,the error of the attitude test system was difficult to be reduced by the huge hardware circuit.For this problem,the method of pre-test calibration is adopted,that is,calibrate the inertial measurement unit and modify the measurement results collected by the acquisition module to fit the actual signal as closely as possible.As can be seen from the analysis of the experimental data,the calibrated system has an accuracy of 1~2 orders of magnitude for the acquisition of the carrier attitude.The experimental results show that the method is effective and feasible in terms of theory.
