Pulse-to-Pulse Coherent Doppler Measurements of Waves and Turbulence

  title={Pulse-to-Pulse Coherent Doppler Measurements of Waves and Turbulence},
  author={Fabrice Veron},
This paper presents laboratory and field testing of a pulse-to-pulse coherent acoustic Doppler profiler for the measurement of turbulence in the ocean. In the laboratory, velocities and wavenumber spectra collected from Doppler and digital particle image velocimeter measurements compare very well. Turbulent velocities are obtained by identifying and filtering out deep water gravity waves in Fourier space and inverting the result. Spectra of the velocity profiles then reveal the presence of an… CONTINUE READING
