Abstract:

The design and preliminary performance characteristics of a variable-reference-level correlator VRLC are described. This unique instrument utilizes the basic circuitry of a digital polarity-coincidence correlator but, by comparatively simple modifications, permits an output to be obtained that is related not only to the phase coincidence of the inputs but to their amplitudes as well. The VRLC has been successfully employed in an experimental program to study the correlation properties of the underwater diffraction pattern of a corrugated airwater interface. Author
