Brillouin optical time-domain analyzer (BOTDA) assisted by echo state network (ESN) for fast and accurate temperature extraction is proposed. Compared to curve fitting methods, the processing speed of proposed ESN algorithm is accelerated up to 20 times. Experimental work is carried out and verified with good agreement of the simulation results.
