摘要
根据三通道偏振导航传感器模型的测量原理,对模型中影响测量精度的偏振正交误差进行了分析和研究,推导出了三通道间偏振光轴的正交误差、定位初始角与定位角测量误差间的关系模型,对构建偏振导航定位系统具有重要的实际指导意义。
The measuring principle of the tri-channel polarization navigation sensors is analyzed. And the error of polarization quadrature is studied, which can affect the measurement accuracy of the model. An error model is designed by strict formula deducing. The relations of tri-channel quadrature error, initial azimuth error and polarization azimuth error are resolved by using error model. This model has guide significance for constructing the polarization navigation sensors.
