Radio frequency scattering from a heated ionospheric volume: 2, Bistatic measurements

Abstract

A variety of bistatic experiments which were carried out for the purpose of determining the scattering properties of the heated inospheric volume in the F layer over Platteville, Colorado, are described. Results are presented on the basis of which it was first determined that the center‐line scattering takes place from elongated field‐aligned scattering structures. Measurements are presented showing that, for the center‐line mode, the scattering of the incident signal consists, effectively, of specular reflections off the geomagnetic field lines.
