In science:

Since the 1960’s the basic system for collecting radio signals has been the dish antenna.
Angular Momentum of Electromagnetic Radiation. Fundamental physics applied to the radio domain for innovative studies of space and development of new concepts in wireless communications
Dish antennas are large and bulky, requiring a lot of material and mechanical engineering, and to point them in different directions one has to physically rotate or move them, a slow process likely to cause loss of unexpected transient signals.

This makes dish antennas unpractical and very costly.

The system temperature can then be derived from the difference in ADC counts between the peak induced by the Sun and the baseline. A patch antenna located at the center of the 4.5 m dish is used to generate RF signals of known intensity, thus performing a relative calibration of the individual feed channels.
