abstract = "We introduce the Raman amplification to increase the sensing range in the Brillouin optical correlation domain analysis (BOCDA). Compared to our previous report, the optimized Raman pumping scheme is numerically simulated and enhanced sensing length is experimentally demonstrated. The differential measurement method and time-domain data processing are further introduced in the backward distributed Raman pumped BOCDA system for the performance improvement. Strain changes of 1 mϵ over 7 cm have been measured at 52 km sensing fiber.",
