Modified Chirp-Z pulse detector

U.S. Patent Number: 5388121

Abstract: A circuit is disclosed for deriving a modified Chirp-Z transform that focs on a narrow bandwidth within a solitary time interval and thereby assures RF pulse detection with the characteristic gain of conventional Chirp-Z transforms. RF pulse detection bandwidth enhancement is accomplished with this circuit by arranging it in a plurality of parallel channels which each relate to one RF pulse frequency within that bandwidth.
