This test operations procedure TOP describes general guidance for determining and evaluating the technical performance and technical characteristics of Direction Finder Sets, Radio. A Direction Finder Set consists of three basic elements a directional antenna, radio receiver, and an indicator. The directional antenna provides a means for locating the wave front since the antenna output varies with the orientation of the antenna relative to the wave front. The radio receiver selects and amplifies the desired signal, and the indicator tells the operator when the plane of the antenna is parallel to the wave front. Originator-supplied key words include Crossed-Adcock Antenna, Goniometer, Wave Front, Cinethedolite Tracking Instrumentation, Bearing Accuracy, Airborne Emitter, Multiple Bearing, Dynamic Range, and Spurious Response.
