Abstract :
The principal sources of antenna noise are discussed together with their effects on antenna performance and methods of reducing these effects. The concept of antenna gain-temperature ratio is introduced and a mathematical method of handling it as a single design parameter evolved. Some limitations of very large continuous apertures are considered and a multielement system proposed as a means of increasing the useful size of large antennas. The performance of some typical arrays is discussed.
