Prediction Unwrapping Algorithm with Linear Kalman Filter to Expand the Dynamic Range of Phase-Sensitive OTDR

Prediction unwrapping algorithm with linear Kalman filter is proposed to overcome the limitation of the conventional unwrapping algorithm in phase-sensitive OTDR. The experimental results show that the dynamic range increased by five times.
