Theory of the diode surface-wave storage correlator

A detailed theoretical study for the operation of the surface-acoustic-wave diode storage correlator is presented. A circuit model describing the device is developed which is used to analyze the signal storage characteristics and the different read-out modes of operation for both p-n and Schottky diode structures. The calculated predictions of the proposed theory are in excellent agreement with experimental data published by independent researchers. The theory presented is self consistent and takes into account, for the first time, the minority carrier lifetime in the dynamics of charging the p-n diode structures which was neglected in previous theories. A straightforward transmission line theory approach is developed for finding the surface-wave amplitude excited by the diode potential during the read-out process. The frequency response characteristics predicted for these structures is a fairly slowly varying function of frequency; hence such correlators are essentially bandlimited by the input and output surface-wave transducers.
