FIELD: the invention refers to the field of radio technique namely to radio navigation.
SUBSTANCE: the direction finder with suppression of modulation of mistakes of direction finding has a non-directed antenna and a group antenna with switching diagram of direction. In totality they form an antenna system with a cardioid diagram of direction switched by a commutator; the first and of the second radio receivers, a bearing calculator and a computer of signals. The technical result is suppression of modulation mistakes of direction finding brought about by a bearing signal spectral components whose frequencies are near to the rotation frequency of an amplitude phase meter of a Doppler navigation direction finder.
EFFECT: suppression of direction finding mistakes.
