Abstract
In this paper, a new method of estimating the spatial directivity (in the form of center-to-limb variation) of microwave burst emission is proposed and derived. Estimations of radioemission directivity values vs observation frequency are obtained. Results are compared to the radio source model using an inhomogeneous magnetic field, source size and particle density, and show a high degree of agreement. Values of model parameters from earlier estimations are confirmed.
