Completion is reported for the Very Large Array (VLA), which consists of 27 25-m-diameter antennas linked by a waveguide system along each of the three arms of a Y-shaped configuration. The four possible antenna configurations correspond to the 1.0, 3.5, 10 and 35 km sizes which permit comparable resolutions to be obtained for the 1.3, 2, 6 and 21 cm primary wave-lengths. The basic principle of operation for the VLA is aperture synthesis, which is based on the fact that the cross-correlation of signals between any two antennas is a measurement of a complex visibility that can be expressed in two-dimensional approximation. VLA observations are to be conducted for extragalactic radio sources, radio emission associated with stars, radio spectral lines, solar system radiation belt mapping, and solar flare site emissions. Resolution from 0.05 arcsec to several arcmin is obtainable.
