Acoustic Velocity Correlator.
Abstract
The program has demonstrated the feasibility of implementing a 16 input x 16 output channel velocity correlator network of a Pulse Burst Processor System using acoustic surface waves. The acoustic velocity correlator is a network of multiple tapped delay lines which corrects the Doppler time shifts of the output signals from a pulse burst tapped delay line and sums the corrected signals in a single Doppler velocity channel. A 50 MHz bandwidth, 8 x 9 channel prototype device was developed on this program which demonstrates the feasibility of implementing a 16 x 16 channel velocity correlator. One of the most important achievements of this program was the development of a technique to fabricate high frequency surface wave transducers by direct projection of oversized patterns onto a substrate over a 1 in x 1 in area. This report describes the design, fabrication, and testing of the 8 x 9 channel prototype device.
