| Abstract: |
This lecture covers the fundamentals of observations with a filled aperture antenna, basic receiver systems and sources of noise. A simple derivation is provided for the radiometer equation, which determines a telescope's ability to detect radio sources. The lecture ends with a discussion of antennas as filters on the spatial Fourier components of the sky brightness distribution. |
