DEVICE FOR CONTROLLING OPERATION OF RADIO STATION WITH PSEUDORANDOM OPERATIONAL FREQUENCY READJUSTMENT Russian patent published in 2009 - IPC H04B17/00 

FIELD: radio engineering.

SUBSTANCE: present invention relates to radio engineering and can be used for detecting broadcast of a radio station with pseudorandom operational frequency readjustment, their direction finding and determining the frequency spectrum used. The device for controlling operation of a radio station with pseudorandom operational frequency readjustment contains a first receiving antenna, second receiving antenna, made in form of a vibrator and frame antenna, a unit for controlling directional pattern, two memory blocks, frequency metre, three radio paths, four amplitude detectors, a heterodyne, a saw-tooth voltage generator, stopping pulse former, threshold block, dividing circuit, commutator, observation oscilloscope, three narrow-band filters, six phase inverters, nine adders, four band-pass filters, two 90° phase shifters, seven keys, time interval measuring device, comparator unit, input device, phase detector, unit for generating control voltage, motor, platform, reduction gear and an angle indicator.

EFFECT: more functional capabilities through controlling operation of mobile radio stations with pseudorandom operational frequency readjustment.
