FIELD: radio engineering, communication.

SUBSTANCE: device for determining the location of the signal source includes the first antenna, the first and the second micromanometry, five analog-to-digital converters (ADC), a single time system unit and a unit of communication with subscribers, connected in series to the first amplifier, the first filter, the second amplifier, the first threshold unit and an OR circuit, the series-connected second antenna, the third amplifier, the second filter, the fourth amplifier and the second threshold unit connected in series to the third antenna, the fifth amplifier, the third filter, the sixth amplifier and the third threshold unit, the seventh amplifier, the fourth filter, the eighth amplifier, the fifth filter, the fourth threshold unit and the first AND circuit, in series connected the first digital-to-analog converter (DAC) and the first calibrator, in series connected the second DAC and the second calibrator, in series connected the third DAC and the third calibrator, in series connected the fourth DAC and the fourth calibrator, in series connected the fifth DAC and the first generator, in series connected the sixth DAC and the second generator, in series connected the first timer, the second AND circuit and the first counter, in series connected the ninth amplifier, the sixth filter, the tenth amplifier, the seventh filter, the fifth threshold unit and the third AND circuit, in series connected the seventh DAC and the fifth calibrator, in series connected the eighth DAC and the third generator, in series connected the second timer, the fourth AND circuit and the second counter, and a clock oscillator, the third and the fourth timers, in series connected the first unit of narrowband amplifiers and the first ADC unit, in series connected the second unit of narrowband amplifiers and the second ADC unit. The first, the second and the third antennas are made magnetic and placed mutually perpendicular to each other. The first, the second and the third drivers are configured as a smoothing link with a power amplifier, the first, the second, the third, the fourth and the fifth threshold units are controlled with a threshold control, the first, the second, the third, the fourth, the fifth, the sixth and the seventh filters are controlled by the first, the second, the third, the fourth, the fifth, the sixth, the seventh, the eighth, the ninth and the tenth amplifiers are configured with phase and sensitivity controls, the first, the second, the third and the fourth timers are designed to control the duration of the output signal, the first and the second three-way ADC units are formed, the first and the second units of three-way narrowband amplifiers made with the sensitivity control, the mean frequency and bandwidth.

EFFECT: reducing the error when used at a single-point surveillance station or vehicle and increasing the noise immunity of the device in the presence of interfering signals from other signal sources.
