Title: Interference rejecting logarithmic receiver

Abstract: 1. A pulsed signal receiver comprising A pair of antennas having non-identical radiation characteristics for receiving desired pulsed signals and interfering signals of higher duty cycle than said desired signals, A pair of logarithmic receiver channels respectively coupled to said antennas, Means coupled to said channels for differentially combining the outputs thereof, And a fast time constant circuit coupled to the output of said differentially combining means, said circuit being adapted to transmit said desired signals and to reject all other signals having a duty cycle higher than that of said desired signals.
