Direction finding is important for civilian, defense, and law enforcement purposes. It involves the use of specialized instruments, antennas, and methods to determine the physical location of a source of RF energy or target. A radio direction finder estimates the direction of an emitter by measuring and evaluating electromagnetic field parameters. This 10-minute audio-visual presentation looks at direction-finding methods, applications, configurations, and benefits. Viewers will be able to submit questions and download a new Rohde & Schwarz white paper that is an essential resource for understanding all aspects of direction finding.
