A Method of Calculation of the Solar Radio Flux Density for High Spatial Resolution Observations

In this paper we present a method of calculation of the flux density of radio source for high spatial resolution solar radio observations, i.e., according to the observed solar antenna temperature, we make a correction for the K factor of antenna power pattern, then we can obtain values of solar radio flux. According to models of different brightness temperature distributions of the quiet sun and radio sources, we deduced the expression of the K factor of antenna power pattern, and calculated the fluxes of the quiet sun and slowly varying component emission of radio sources at 22 GHz.
