ABSTRACT:
1. A correlation system for two complex multifrequency input signals which may contain relatively strong narrow band components including the combination of: auto-correlator means responsive to one of the input signals, the auto-correlator means dividing the one input signal into two channels and including delay means in one of the channels for introducing a fixed relative timing displacement between the two signals, threshold means coupled to the auto-correlator means for indicating when the auto-correlation output signal exceeds a selected amplitude, first and second delay means each responsive to a different one of the input signals and introducing like delays thereto, gating means coupled to at least one of the delay means and controllably responsive to the threshold means, and correlator means coupled to said delay means and said gating means for correlating the two input signals therefrom.
