Query: Detection of Moving Targets using Coherent Optical Frequency Domain
  Reflectometry   We present Doppler-corrected position and velocity measurement with a
fiber-coupled COFDR system based on the FMCW radar principle for high precision
localization applications. A high measurement accuracy and the ability to track
targets are demonstrated.
