The Development of Surface Wave Dispersive Filters for Use in a Multichannel Pulse Compression System
Abstract
The technology and understanding of acoustic surface wave devices has progressed to the point where they can be used to implement sophisticated processing schemes such as a parallel channel pulse compression filter. The report discusses the design, development and experimental verification of the surface wave dispersive networks necessary to build a 7-channel pulse compression filter with 700 MHz bandwidth and a TW product of 4900. These individual channel filters must be time contiguous with identical linear FM dispersive characteristics. A division synthesis technique is developed for the realization of these filters. The technique is specifically tailored for an acoustic surface wave implementation consisting of one apodized and one unapodized transducer. The resulting filters were quite reproducible and their general characteristics (spectrum shape, bandwidth, and dispersive delay) were essentially as desired.
