AI 中文摘要
信号衰落会导致光纤上部分点无法提取相位，传统方法会丢弃这些点；我们提出一种基于卡尔曼滤波的{\boldsymbol{\text{Kalman}}}-{\boldsymbol{\text{OTDR}}}全光纤监测方案，实验显示其相位与温度估计的空间密度比丢弃这些点时提升约15倍。
英文摘要
Signal fading creates points along the fiber where phase cannot be extracted, so they are conventionally discarded. Instead, we propose a Kalman-based solution for ϕ-OTDR full-fiber monitoring. Experiments demonstrate phase and temperature estimation with approximately 15 times better spatial density than if removing these points.
