Paper Abstract

The Acousto-Optic Precision Direction Finding (AOPDF) system is a demonstration EW receiver in development at the Naval Research Laboratory as a DARPA sponsored activity. A two-dimensional Acousto-Optic processing element extracts frequency, angle of arrival (AOA), and time of arrival (TOA) on a pulse-by-pulse basis. Performance advantages achieved through use of Acousto-Optic technology include a wide instantaneous RF bandwidth, multiple simultaneous signal capture, and accurate AOA measurement over a quadrant field of view. This paper describes the conceptual design, system development, and evaluation of a demonstration unit based on the AOPDF concept.
