Abstract
Refinements in direction finders, characterized by a direction finding receiver of the class in which the direction-sensitive received signals are combined with omni-directional received signals, in a combiner circuit, in order to provide an automatic direction and direction indication to the time and in which the received signals, sensitive to the address, are prepared to be introduced into the combined circuit mentioned through a channel that includes a phase splitter whose input is fed with the received signals sensitive to the direction, the splitter phase has two outputs in which the signals appear in phase opposition, a pair of pole rectifications arranged in opposition, a rectifier with a pole powered from one of the outputs and the other rectifier, equipped with a pole installed, fed from the second output, the remaining poles of the rectifier are prepared to feed a common point a potential spring it is relatively low frequency modulation, means to apply the modulation potentials coming from the source, in phase to the first mentioned poles, of each of said rectifiers and means to introduce into the combined circuit mentioned the balanced modulation waves that appear in the aforementioned common point.
