中文摘要：
偏振正交误差是影响四通道时分复用大气偏振检测系统精度的主要因素。通过建立检偏器阵列偏振正交误差对偏振光导航系统定位精度的影响模型，分析了该误差对大气偏振测量精度与导航定位精度的影响，并进行了实验验证。理论与实验结果表明，降低检偏器阵列偏振正交误差，可以显著提高系统大气偏振测量精度与导航定位精度。当检偏器阵列偏振正交误差无法消除时，调整定位初始角可以明显提高系统测量精度与导航定位精度。
英文摘要：
Pattern measurement accuracy is mainly depended on polarization analyzers array perpendicular error. Based on a developed four-channel time division multiplexing skylight polarization measuring system, a polarization perpendicular error model is proposed. Effects of error on the measurement accuracy are analyzed theoretically and investigated experimentally. The results show that when the polarization perpendicular error is reduced, the measurement accuracy of skylight polarization patterns and system positioning accuracy are improved greatly. When the error exists and cannot be eliminated, the adjustment of initial angles of polarization analyzers can improve dramatically the measurement accuracy of the system.
