Abstract
Present-day processing requirements for radar and communication signals range from real-time, large bandwidth to large processing gain, all in a dense multisignal environment. By combining desirable features of acoustics and optics and in some cases charge-coupled devices (CCD), acousto-optic technology offers great promise of fulfilling these diverse requirements. This paper overviews some of the uses of acousto-optic technology, especially those using surface acoustic wave (SAW) devices in the areas of radar and communication signal processing. Two areas are covered, (1) Fourier transformation, including spectrum analysis, and (2) correlation.
