Abstract
A self synchronizing convolver system includes a surface acoustic wave convolver excited by an appropriate reference such as an even function waveform so that the reference waveform is combined with the signal waveform in a manner yielding the complete correlation function independent of the time of arrival of the signal thereby permitting asynchronous operation.
Claims1
A self synchronizing convolver system comprised of a transmitter, a first antenna associated with said transmitter for transmission of radiant energy therefrom, an even function generator providing a modulating signal to said transmitter, a receiver, a second antenna assoicated with said receiver, said second antenna rceiving resultant radiant energy from the transmission, means to power split the output signal from said receiver into first and second portions, a convolver having first and second inputs and a parametric region, delay means having a preselected delay equal to one-half modulating signal length T, said first portion passing through said delay means to said first input of said convolver and said second portion being fed directly to said second input of said convolver, with the output signal being provided by way of said parametric region.
