摘要

An Acoustic Sounder System has been installed on the side of the cliff at North Oscura Peak, WSMR to provide important refractive index structure parameter, Cn~2 data for laser propagation tests. The acoustic sounder system records echo information that is used to provide 3 dimensional wind and optical turbulence profiles. The received signal is the product of the interaction of the transmitted acoustic pulase with the small scale atmospheric temperature variations. This informaiton is displayed as a time-higher display of the signal intensity. The frequency of the received signals are processed and converted into time histories of the horizontal wind field.
