全角模式半球谐振陀螺的信号检测法研究

Signal Measuring of Hemispherical Resonator Gyro(HRG) Based on Whole Angle(WA) Mode

半球谐振陀螺由于制造工艺和其它因素的影响,其结构难免出现误差,会对测量结果产生影响,同时漂移的存在也会降低测量结果的精度。通过对结构误差和漂移的分析,介绍了一种全角模式下半球谐振陀螺的信号检测方法。这种方法可有效地使输出信号精度得以提高。

According to basic principle and actual feature of HRG（Hemispherical Resonator Gyro） , the paper introduces signal measuring method of HRG based on whole angle mode. Due to some factors induced by fabrication technology and other reasons, the structure error and drift are inevitable , they affect measuring result and reduce accuracy. By analyzing structure error and drift , a kind of signal measuring method is proposed , this method can effectively improve the accuracv of output signal.
