SCATTERING OF ELECTROMAGNETIC-WAVE BY RADIALLY INHOMOGENEOUS-PLASMA CYLINDER WITH FLUCTUATIONS OF THE ELECTRON-DENSITY

The problem of radio signal passing into the region of caustic shadow formed behind the radially inhomogeneous plasma cylinder with statistical isotropic quasi-homogeneous fluctuations of the electron density is considered. It is shown that the field intensity increases in the region of caustic shadow in the presence of fluctuation in the plasma cylinder. Dependences of intensity of the field in the region of shadow on the distance to the region with critical density of electrons and on the intensity of fluctuations of the density of electrons are given. The character of behaviour of the mean intensity is considered on the caustic and in the vicinity of the caustic in the presence of fluctuations in the plasma cylinder.
