In this paper, introduced the sensor sensing principle for back Brillouin scattering distributed optical fiber . making the experiment and reseach on Brillouin scattering based distributed fiber optic sensor system 。explanation on the Fiber-optic sensors on the classification and characteristics of distributed fiber optic sensor and the latest trends.Furthermore，introduce the working principle of distributed Brillouin fiber-optic sensorwhich is based on BOTDA technology 。 By the analysis the signal characteristics of fiber-optic Brillouin backscatter which is detected, make a research and comparea variety of detection methods of weak signal , the selected digital signal multi-point average (Digital BOXCAR) program to improve the processing of the signal-to-noise Brillouin scattering . Through the method of fitting the equivalent pulse Brillouin distributed optical fiber to improve the spatial resolution sensors.
