Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. Understanding the effects of varying conditions on radio propagation has many practical applications, from choosing frequencies for amateur radio communications, … WebSeptember 8, 2000 Basics of Radio Interferometry [AF] 4 The Solution + There is a way to build big radio telescopes:! take several “small” telescopes in great distance from one another! combine their output signals in an appropriate way! do some computing on the results That is a very simplistic view of a radio interferometer
