AB - A number of requirements exist for processing signals of very long duration and moderate bandwidth (~10 MHz), such as in high resolution radar and secure communications systems. Acousto-optic methods have been known for many years, but have not been adopted in practice largely due to the simplicity of acoustic surface wave devices. Acousto-optic processors are, however, competitive, where very long storage times, up to one millisecond, are re-required. We have built delay lines with paths folded in two dimensions for storage up to 350 microseconds, and delay lines folded in three dimensions with storage near one milli-second. The acousto-optic processor was applied to the demonstration of synchronization and detection of data of a secure communications system, and also to the cross-correlation of a Barker coded signal with a set of Doppler shifted references.
