Unwrapping methods based on wavefront time-domain detection algorithm

Presents two phase-unwrapping methods based on wavefront time-domain detection, of which one is the spatial-domain phase-unwrapping method, the other is time-domain and spatial-domain phase-unwrapping method. By changing the amplification and frequency of the external noise environment, the measurement accuracy, anti-jamming ability and efficiency of the wavefront time-domain detection algorithm is studied in various external noise environments. It showed that both methods can achieve higher measurement accuracy and better anti-jamming ability, but that the latter has higher measurement efficiency and faster measurement speed.
