Signal Processors Based on Combined Charge Coupled Devices and Surface Acoustic Wave Devices,

Abstract

Signal processors based on combined Charge Coupled Device (CCD) and Surface Acoustic Wave (SAW) components are reviewed. Emphasis is placed on the realization of wide bandwidth (10 MHz) Fourier transform processors, with many transform points (> 1000). Design approaches interfacing untapped CCD shift registers for time compression with SAW chirp transform processors are reported. Other designs based on multiplexed CCD, CZT's or Coherent Memory Filters are also described. These CCD-SAW Fourier analysers are shown to have application as temporal processors for Radar Doppler filtering. The potential impact of one and two dimensional spatial transform processors for Sonar beam forming is also examined. (Author)
