title: [Unambiguous turbulence measurement method and system using transverse Doppler techniques].
abstract: This paper introduces the principle of Doppler ambiguity process and the ambiguity reduction techniques using dual-sample volume. An unambiguous fluid turbulence measurement method using transverse Doppler and dual-sample volume cross-correlation techniques is described. An experimental turbulence detection system is designed. Theoretical and experimental results show that this method can eliminate the Doppler ambiguity spectra produced by transit-time effect, turbulence and velocity gradient in sample volume.
