Haystack Observatory

Abstract

Among the 32 presently active radio astronomy programs, 15 are spectral line research, 8 involve continuum measurements, 2 are Haystack-Westford short baseline interferometer projects, 5 are VLBI experiments and 2 used the spectrometric receiver with a small horn antenna. Radiometric programs involve the planetary radar, and 2 of these use the Haystack-Westford interferometer to receive the echoes.
