FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a class of systems which measure the direction of an object. The disclosed direction-finder comprises a direction-finding antenna, an angle sensor, n compensation antennae, n+1 superheterodyne receivers with a common heterodyne, a non-search receiver, a processing unit, a YIG band-rejection filter, a current frequency value label former, a "start" label former, an "end" label former, a frequency referencing unit, a YIG transmission filter and a digital-to-analogue converter, connected to each other in a certain manner.
EFFECT: high probability of finding the direction of signal sources with a carrier frequency that is constant or varies from pulse to pulse.
