The WAVES instrument onboard the 3 axis stabilized STEREO spacecraft is composed of a set of 3 monopole antennas connected to a radio receiver. The receiver measures spectral and cross-spectral power densities on one, two or three antennas in the frequency range between 10 kHZ and 16 MHz. This package will therefore have direction finding (DF) capabilities, allowing to determine the direction of arrival of an incoming wave, its flux and polarization properties. A DF analytical model has been recently developed and applied to the CASSINI/RPWS data in order to perform DF on localized Jovian radio-emmission (Cecconi et al., xxx) We present an extension of this latter model for extended solar radio emmission such as type III and type II bursts, produced respectively by subrelativistic electrons travelling outward along open magnetic field lines to lower densities in the IPM and by solar wind electrons accelerated by transient shocks moving outward from the Sun to the IPM.
