half-power beamwidth
(HPBW)

subject fact

half-power beamwidth has acronym HPBW has source: Lena, P., Lebrun, F., Mignard, F. 1996 Observational Astrophysics, Springer, 2001-09-27 09:33:30.0
has definition The angle across the main lobe of an antenna pattern between the two directions where the sensitivity of the antenna is half the value at the center of the lobe. This is the nominal resolving power of the antenna system. has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:33:30.0
