Abstract:

The theoretical considerations involved in the operation of a radio frequency interferometer, in which the IF output signals from receivers at spaced sites are correlated by analog multiplication, is presented. The multiplier output can be resolved into plots of relative signal strength and phase the latter being a function of the direction of arrival of the source wavefronts. A simple form of short baseline system in which the signal delay is under 3 microseconds and the fringe rate is less than 1 cycle per minute, is discussed. Through the introduction of a phase-locked offset in one of the intermediate frequencies it is possible to record the correlation output for later plotting or analysis. Author
