Paper Abstract
The signal-to-noise ratio (SNR) enhancement using a coded pulse in Brillouin Optical Time Domain Analysis (BOTDA)
is studied theoretically and experimentally and compared with the one pulse case. This new technique is based on
simplex coding and provides a theoretical SNR enhancement of 3.6 dB. We find that the experimental SNR
improvement is around 3.8 dB, which is in good accordance with the theory. We also observe that the Differential
Pulsewidth Pair - Brillouin Optical Time Domain Analysis (DPP-BOTDA) method can be applied. This allows to
combine high spatial and frequency resolutions1 and higher SNR.
