Abstract
In this study, the fluctuation ranges and mean values of solar brightness temperatures at microwave frequencies are estimated using solar radio emission fluxes at 2800 and 8800 MHz measured through several solar cycles. These variations include both short-term (daily) and long-term (11-year solar cycle) changes. The corresponding antenna noise temperatures at S-, X-, and Ka-bands are calculated for various antenna beamwidths and pointing offsets. The results are applied to the link design for a Lagrangian-orbit mission with a low-gain antenna at S-band.
