Scientific paper

We present simultaneous observations of an interplanetary type II radio burst and a pair of type III radio bursts by the Ulysses and Wind spacecraft separated by more than 100 degrees in heliographic longitude. We investigate the roles of refraction and scattering in the widespread visibility of these radio emissions, by using statistical ray tracing techniques. The raytracing computations in smoothly varying solar wind plasma with low levels of density fluctuations show that the fundamental becomes more directive than the harmonic emission because of refractive focusing. The scattering of radio waves by density fluctuations in the solar wind is simulated by randomly sampling the polar and azimuthal angles of the direction of the ray following each scattering event as well as the path length between consecutive scattering sites. The computed directivities of radio bursts due to refraction and scattering are shown to be easily accounting for the observed widespread visibility of radio bursts. The directivities obtained by the present method are compared and contrasted with those obtained by previous authors using the traditional Monte Carlo method.
