Simulation and experimental results have shown that the combination of two kinds of codes to modulate phase-shift pulse Brillouin optical time domain analysis (PSP-BOTDA) pump pulse for distributed strain measurement provides higher SNR than that of using only one code system, and better spatial resolution than dual Golay codes PSP-BOTDA. In preliminary experiments, 10cm spatial resolution measurement was demonstrated.
