Effect of intermittency of turbulence in the atmosphere on radio-wave scattering
Abstract
The intermittency of atmospheric turbulence is studied on the basis of airborne measurements of the LF component of temperature pulsations. The theory of radio-wave scattering in the atmosphere is extended to turbulence whose parameters are random functions. A measure for the random value of turbulence intensity in a scattering volume is introduced, and probability distributions for observed scattering cross sections are obtained. An investigation using the log-normal distribution shows that turbulence intermittency can be one of the causes of point-type radar reflections.
