The invention discloses a calibration system applied to dust cloud concentration field distribution and a method of the calibration system. An ultrasonic pulse concentration calibration system is provided, a relation between dust concentration and an energy attenuation coefficient is obtained, pulse ultrasonic sensor detection units are distributed in the whole dust cloud diffusion space, a pulsevoltage signal is used for simulating an emission sensor to generate an ultrasonic wave, the ultrasonic wave penetrates through an attenuation oscillation pulse region to form an attenuation oscillation pulse wave, the calibration system has high interference-resistance capability and convenience of a test system, dust cloud is generated during the dust detonation process and are diffused and penetrates through a unit field attenuation oscillation pulse region to cause that the attenuation oscillation pulse wave energy is reduced, and a computer is used for calculating to obtain the energy attenuation coefficient acco
