Large Antennas of the Deep Space Network by William A. Imbriale
English | PDF | 2003 | 307 Pages | ISBN : 0471445371 | 18.9 MB

An important historical look at the space program's evolving telecommunications systems
Large Antennas of the Deep Space Network traces the development of the antennas of NASA's Deep Space Network (DSN) from the network's inception in 1958 to the present. It details the evolution of the large parabolic dish antennas, from the initial 26-m operation at L-band (960 MHz) through the current Ka-band (32 GHz) systems. Primarily used for telecommunications, these antennas also support radar and radio astronomy observations in the exploration of the solar system and the universe. In addition, the author also offers thorough treatment of the analytical and measurement techniques used in design and performance assessment.
