Abstract
A difference-in-time-of-arrival direction finder includes auto-correlation means that includes means for substantially reducing, at the output of the auto-correlation means, the unwanted noise power of all uncorrelated unselected incoming radio-waves received at two spaced antennas that arrive from any direction other than a certain direction with respect to the wanted signal correlated power of that selected one incoming radio-wave arriving from the certain direction with respect to the line connecting the antennas specified by a given signal time delay provided by a delay line associated with one of the antennas.
