The Mobile VHF-UHF Communications Intelligence (COMINT) Complex is intended for the position finding and recording the radio frequency radiation sources within the frequency range of 30 MHz - 3000 MHz.


The Mobile VHF-UHF Communications Intelligence (COMINT) Complex is intended for the position finding and recording the radio frequency radiation sources within the frequency range of 30 MHz - 3000 MHz.

Complex consists of three identical Mobile COMINT Stations mounted in the shelter, which can be installed on the platform of the truck or on the trailer.



The Mobile COMINT Station includes:

1. Direction finding (DF) antenna system. Which is implemented on the basis of two 9-element ring antenna arrays operating within the frequency range 30-600 MHz and 600-3000 MHz. The mast with the antenna system is automatically raised into position by the driving mechanism.

2.     Conversion and digital signal processing block;

3.     Automated workstations of operators;

4.     Power supply and life-support equipment;

5.     Radio communications equipment;

6.     Survey control equipment. MAIN FUNCTIONS OF COMPLEX


•  Automatic detection and analysis (measurement of parameters) radio signals in the preset frequency band.

•  Automatic direction finding of detected radiation sources.

•  Executive direction finding (by command from the outside) or command forming on direction finding for another station.

•  Formation of amplitude frequency (spectral) panorama of the whole range or the separate bands, as well as the amplitude-frequency- time panorama (in the 5 MHz band).

•  Formation of DF (amplitude-frequency-azimuth) panorama of the whole range or the separate bands.

•  Calculation of the radio sources coordinates and the formation of radio environment map on the basis of terrain map.

•  Demodulation of radio signals in real time or previously recorded.

•  Formation of database with results of the detection, analysis, demodulation, direction and position finding.

•  Check of equipment service capability using built in control elements.
