Coherent integration and correlation in a modified acoustoelectric memory correlator

Abstract

The storage, correlation, and coherent integration of analog signals in a Schottky diode acoustoelectric memory correlator is described. The experiments demonstrate storage of phase and amplitude of a 70‐MHz signal by the distribution of charge in an array of Schottky diodes. Coherent integration is obtained by accumulating a succession of charges in highly resistive polycrystalline silicon islands. Coherent integration over a time period of several tens of milliseconds is reported.
