Radar Detection of Turbulence in the Upper Troposphere 660187
Encounters of jet aircraft with high altitude turbulence prompted the investigation of various techniques to probe and locate turbulence in areas lacking particles (rain drops, hailstones). A promising technique is to measure the radio refractive eddies and gradients by radar backscatter. Radio refractive index eddies can, in principle, be found where an atmosphere characterized by a nonadiabatic lapse rate of refractive index is stirred up by turbulence.
A sequence of VHF backscatter experiments which will hopefully lead up to an airborne CAT detector are presented in this paper.
