DEVICE FOR MONO-IMPULSE MEASUREMENT OF BEARING OF RADIO SIGNALS SOURCES Russian patent published in 2006 - IPC G01S13/44 

FIELD: radio engineering, possible use for determining bearing and frequency of radio signals in radio control systems.

SUBSTANCE: known device for mono-impulse measurement of bearing of radio signals sources contains two identical receiving antennas, directional diagrams of which are shifted one relatively to another for angle, not exceeding their width, first high frequency amplifier, input of which is connected to output of first receiving antenna, second high frequency amplifier, input of which is connected to output of second receiving antenna, connected serially: first amplitude detector, first video amplifier and first analog-digital converter; connected serially: second amplitude detector, second video amplifier and second analog-digital converter and calculator, first and second inputs of which are connected to outputs of, respectively, first and second analog-digital converters. Introduced to known device are: two power dividers, frequency meter and phase difference meter, input of first power divider is connected to output of first high frequency amplifier, first output - to input of first amplitude detector, while second output - to first input of phase difference meter, input of second power divider is connected to output of second high frequency amplifier, first output -to input of second amplitude detector, while second output is connected to second input of phase difference meter, output of which is connected to third output of one of power dividers, while output is connected to fourth input of calculator, while receiving antenna mouth centers are positioned at distance not less than 5...10 times greater than wave length of radio signal being located.

EFFECT: increased precision in comparison to prototype when determining bearing of radio radiation source; device also determines frequency of radio signal without additional receiving antennas and high frequency amplifiers.
