“…3) Figure ofMerit: One of the more popular specifications of antenna system noise is figure of merit, usually denoted as G/ T [ 1], [3], [23], [25] - [32]. Figure of merit is defined to be the ratio of the antenna receive gain to the system noise temperature (referred to the antenna output port).…”

“…This project was made possible by financial support and the interest of the United States Army Communications Command, Fort Huachuca, AZ. The author is with the National Bureau of Standards, Boulder, CO 80303. a satellite. This satellite signal can be used in a way not too different than that of a radio star [25]. Finally, a modified gain comparison technique can be used where one antenna is basically used to calibrate the strength of some radio source in order to then calibrate a second antenna.…”

This paper reviews the National Bureau of Standards (NBS) preision noise measurements program for antenna systems which have been made using Cassiopeia A and the moon. The Earth Terminal Measurement System (ETMS) was developed by NBS to make measurements of figure of merit (GIT), and the noise equivalent flux (NEF). The accuracy of the noise measurements are, typically, between 5 and 15 percent for systems with antenna gains between 51 and 65 dB and frequencies between 1 and 10 GHz. Key words-antenna gain; antenna half-power beamwidth; atmospheric loss; Cassiopeia A; earth terminal measurement system; figure of merit; moon; noise equivalent flux; noise measurement; radio stars; satellite communication.
