Acoustic Velocity Correlator Development.
Abstract
SURFACE WAVES, SIGNAL PROCESSING, SURFACE WAVESThe doppler velocity correlator is a surface acoustic wave device whose ultimate function is to correct the phases of signals obtained from a pulse burst processor type of multiply tapped surface acoustic wave delay line and to sum these phase corrected signals in a single doppler velocity channel. Because of the need for numerous doppler output channels, the device can consist of many input and output channels. The purpose of the program reported here is to demonstrate the feasibility of this concept. During the first half of the program, a critical design review was conducted; the survey included a critique of the transducer designs for both input and output channels, the tradeoff involved in using transducer position shift or metallization for the doppler phase correction, and an analysis of the electrical-mechanical package design.
