ABSTRACT:
A chirp transform correlator having asynchronous operation is made possible by the use of a pair of paralleled signal processing channels to which the unknown signal to be correlated is applied. The two channels include sweeping local oscillators which are interlaced in timing so that any arbitrarily timed unknown input signal will be fully transformed by one or the other of the channels.
