Scientific paper

Walsh functions can be used to advantage to perform phase switching in
antenna arrays used for radio mapping of the sky by Fourier synthesis.
This paper describes the reason for phase switching, the advantage of
using Walsh functions, and the implementation of these ideas in the Very
Large Array (VLA) program of the National Radio Astronomy Observatory.
