摘要
提出了一种测量超低空风的声探测系统,并介绍了系统组成、系统测风原理等.该系统利用利用相控阵技术形成发射和接收波束,实现5 ～20 m超低空段风的离散测量.
A system of sound detecting about super low section of wind measurement is proposed in this paper, and the system composition, wind measurement and so on are introduced. Phased array detects the Doppler frequency shift of the re- ceived backscattered echo from 5 to 20 miles by emitting a strong acoustic pulse in the audio band to produce need informa- tion.
