Structural Diagram of ARTIKUL-S Direction Finder
Features:
- Two-channel digital radio receiver is installed inside DF antenna system providing for high interference protection, sensitivity and DF accuracy
- To prevent overloading of Direction Finder's digital path in complicated electromagnetic environment, digital radio receiver includes additional analogue paths with 500 kHz bandwidth
- In case of operating frequency range of 20-3000 MHz weight of the antenna system doesn't exceed 40 kg
- The distance between antenna systems and operator's location can be up to 100 m
- Operation as a part of ARCHA-IN stations and ARTIKUL-SN systems.
Direction Finder Provides:
- Panoramic spectrum analysis within the entire operating frequency range or within separate intervals in complicated electromagnetic environment, accommodation to ambient radio environment and detection of its changes
- Search for emission sources within selected frequency ranges, including frequency hopping signals
- Plotting frequency-time diagram of loading within analyzed frequency ranges.
- Automatic direction finding of radio emission sources with random modulation types and spectrum width in single-channel and multi-channel modes
- Selective direction finding of 2G/3G/4G/5G Base Stations
- Selective (time-slot based) direction finding of subscriber 2G terminals (mobile phones, trackers, etc.), operating at the same frequency
- Selective direction finding of Wi-Fi communication devices with recognition of MAC-address, including those that use non-standard frequency ranges
- Building of bearing panorama within operating frequency range
- Real-time display of bearings, spectrum panorama, bearing history and signal amplitude history
- Evaluation of signal parameters
- Field strength evaluation
- Recording of I/Q samples and radio spectra
- Automated radio monitoring based on preset schedule or under operator control
- Automated control of equipment health
- Review and processing of the data from DB
- Mapping DB information on the electronic map
- Generation of reports with radio monitoring results in Microsoft Office, OpenOffice, HTML and PDF file formats.
In case of joint operation, the direction finders provide:
- Interaction via wire and wireless channels
- Assigning tasks from master direction finder to slave ones, being operated within the same system
- Transfer of radio monitoring data from slave direction finders to master one for further analysis and processing
- Synchronous direction finding of radio signal sources
- Transmitter location evaluation based on direction finding data
- Operation of several direction finders (when communication equipment is available) as a part of Automated Spectrum Monitoring Systems (ARMADA, AREAL etc.)
