Through a Turbulent Atmosphere

The sta ti s ti cal di s tributi ons of th e a ngle of arrival, th e s pot location, the cross section, th e amp li . tude , th e carrier phase and the modulation phase of a lase r bea m tra ve rs ing an anisotropicaliy turbule nt at mos phere are de rived in terms of the s pace corre la tio n fun c tion of th e at mosph eri c index of refractio n a nd the windspeed. The Limit a ti o ns imposed by the turbule nt atm osp he re and the loss ,of cohe re nce o n the de pth and bandwidth of the modulation , on the le ngth of the path a nd on the a pe rture of the rece iv· ing appara tus are a na lyzed . Experim e nt s to ob tai n num e ri ca l param e ters a nd tn c hf'c k fun c tional depe nde ncies are proposed.
