φ-OTDR Based on Orthogonal Frequency-Division Multiplexing Time Sequence Pulse Modulation

φ-OTDR Based on Orthogonal Frequency-Division Multiplexing Time Sequence Pulse Modulation

This study introduces an innovative phase-sensitive optical time-domain reflectometer (φ-OTDR) technology based on orthogonal frequency-division multiplexing (OFDM) and nonlinear frequency modulation (NLFM) pulse modulation sequences. The proposed approach addresses the inherent trade-offs among spa...
