Abstract:	Clear air turbulence remains an ongoing concern for aviation, and current detection methods provide poor or unreliable coverage. This paper details a method for the detection of clear-air turbulence using a model for the spectrum of the logamplitude of a signal, derived from weak scattering theory. Also presented is a discusison of methods used for estimation and the estimated parameters. Validation of the method was attempted using in situ measurements of turbulence by commercial aircraft, as well as data derived from MST/ST RADAR sites, with results and methods discussed.
