| Abstract: | this paper proposes a system of sound detecting about super low section of wind measurement, and introduces system composition, wind measurement and so on. Phased array detects the Doppler frequency shift of the received backscattered echo from 5 to 20 miles by emitting a strong acoustic pulse in the audio band to produce need information. |

| Keywords: | system of sound detecting system composition super low section of wind |
