摘　　要：针对光电式偏振光敏感器测量模型中解算偏振度误差较大的问题,考察了最大偏振度所具有的物理特性,借鉴加速度"当前"统计模型的思想,提出一种最大偏振度估计模型,应用于导航方法中。仿真表明该方法能够实现对于速度和最大偏振度的跟踪,在最大偏振度发生变化时有良好的跟踪效果。In order to solve the problem of large error in calculating the degree of polarization of photoelectric polarized light sensor, through investigating the physical characteristics of the maximum degree of polarization, a maximum degree of polarization estimation model based on the idea of acceleration "current" statistical model is proposed, which is applied to navigation. Simulation results show that the velocity and the maximum degree of polarization can be tracked by using this method which has good tracking effect when the maximum degree of polarization is changed.
