RADIO SIGNALS DIRECTION FINDING METHOD. RF PATENT 2262119

The invention is related to radio engineering and can be used in systems of radio signals detection and direction finding.

Design documentation has been developed, radio direction finder samples have been tested (MRP-3 unit) in which the patent 2262119for invention is used. The unit represents small-sized 3-channel direction-finder with two sub band 3-element Wullenweber antenna arrays from vertical symmetrical vibrators with operating frequency ranges from 25110 Hz and 110400 Hz. Due to direction finding method application protected by patent 2262119 in the unit there are practically no system errors which occur because of over radiation of the bearing signal by antenna elements and antenna device mast support. The unit consists of signals reception and processing block fulfilled on BNK Base-3 of III-1dimension type and antenna device with feeders set.
