Disclosed is a random Brillouin dynamic grating generation device, comprising a laser source, 1 × 2 optical fiber couplers, a first electro-optic modulator, a first random optical pulse generator, a first optical isolator, a first erbium-doped optical fiber amplifier, a single sideband modulator, a microwave source, a first polarization controller, a second electro-optic modulator, a second random optical pulse generator, a second optical isolator, a delay optical fiber, a second erbium-doped optical fiber amplifier, a second polarization controller, a polarization beam combiner, and a polarization maintaining optical fiber. In the present invention, two random optical pulses that change randomly and have different repetition frequencies are used as two pump lights, and the two pump lights are respectively injected from two ends of the polarization maintaining optical fiber; polarization directions of the two pump lights are the same, and the frequency difference is a Brillouin frequency ...
