Theoretical and Experimental Results for Monolithic SAW Memory Correlators

Abstract

A detailed theory is presented for the writing and reading processes in the monolithic surface acoustic wave (SAW) storage cor- relator. Theoretical and experimental results are presented on the dependence of the conelation output on the duration of the acoustic, write, and read signals. The dependence of the output on the ampli- tudes of the acoustic, write, and read signals is also given. The theoreti- cal predictions me in good agreement with the experimental results in all of these cases. Suggestions are provided for the design of improved monolithic storage conelators.
