Annotations languages:

The capability of improving of direction finding multichannel radio system characteristics at the expense of additional usage of a redundant information which is obtained on output effects of antenna - receiving channels with near-omnidirectional characteristics in the case of frequency-multi-beam sounding was considered. Discriminator characteristic zero drift effect decreasing is reached on the basis of biased estimator using which are obtained on exits of two angle discriminators. Effectiveness of a method confirms results of calculation and mathematical simulation.
