A simple solution of the problem of scattering of radio waves in successive encounters with a rough earth and an ionosphere which introduces irregularities into the phase is presented. This leads to calculated shapes of the incoming angular power spectrum and of the antipodal area and indicates that, under some special circumstances, an antipodal circle of enhanced signal strength may also be present. Some comparisons are made with a few experimental results.
