Statistical models for D-region partial-reflection experiments


  • Jeffrey H. Shapiro


A phenomenological model for D-region partial-reflection experiments, which includes the effects of turbulent scattering, measurement noise, and coherent returns, is examined. General results for the amplitude and phase-difference statistics of the ordinary- and extraordinary mode signals are obtained. These results are specialized and discussed for cases in which either the measurement noise or the coherent-signal component is insignificant. A possible criterion for discriminating between turbulence models and a single reflecting-layer model on the basis of amplitude statistics is obtained.
