4 signi?cant elements have led us to replace this article. The ?rst is the breathtaking development in know-how, specifically in receiver and electronic strategies. the second one is the development of radio astronomy to shorter wavelengths, and the elevated availab- ity of astronomical satellites. The 3rd is a necessity to reorganize the various chapters to be able to separate the fundamental conception, that seldom adjustments, from useful features that fluctuate usually. eventually, it truly is our wish to increase the textual content by means of together with challenge units for every bankruptcy. In view of this bold plan, we've increased the variety of authors. within the reorganization of this version, we've got divided Chap. four of the 4th version into Chaps. four and five. The ?rst is still Chap. four, with a touch diversified - tle, sign Processing and Receivers: idea. This was once accelerated to incorporate electronic processing and elements together with samplers and digitizers. In Chap. five, Prac- cal Receiver structures. we have now relegated the shows of maser and parametric ampli?er entrance ends, that are now not regularly occurring as microwave receivers in radio astronomy, to a brief part on “historical advancements” and we now have retained and more desirable the shows of present cutting-edge units, cooled transistor and superconducting entrance ends. we've got additionally integrated descriptions of neighborhood oscillators and section lock loops. Chapters five and six within the 4th version has now develop into Chap. 6, basics of Antenna concept and Chap.
