Radio direction finder
|Radio direction finder|
A Radio direction finder locates active radio wave emitters using like Radio Communicators, RADAR, Radio Jammer, and Active EMS arrays. It consists of a receiving array (typically one or more aerials) and a control panel. This is a passive sensor. Introductory version require manually moving a large antenna array to determine direction and relies on operator skill to interpret the results. More advanced versions automate the antenna operation and can track multiple radio sources, categorizing them by type, power, and distance.
