ABSTRACT:
Apparatus for measuring meteorological parameters comprises a laser generator transmitting pulse laser signals which are backscattered at least in part by the atmosphere, a receiver including spectrum filter means that are substantially monochromatic, means for adjusting the center wavelength of the transmitted spectrum and of the received wavelength, and means for analyzing the backscattered signal as a function of altitude, as a function of the doppler shifts between the transmitted signals and the backscattered signals, and variations in said signals as a function of the observation direction.
