ARTIKUL-MT Direction Finder

Options:

  • AS-HP-HF Antenna System for automatic direction finding within 1.5 – 30 MHz, with integrated navigation equipment
  • AS-HP2 Antenna System for automatic direction finding within 3 – 8 GHz, with integrated navigation equipment
  • High-stable external reference generator
  • Vehicle luggage box with fasteners to mount DF antenna systems
  • Communication and data transmission equipment
  • SMO-BS Software Packages for Wireless Data Communication System Analysis: BS 3GPP (GSM, UMTS, LTE), BS CDMA (IS-95, cdma2000, EV-DO), BS TETRA, BS TRUNK (DMR, APCO P25), BS Wi-Fi, BS WiMAX.

Features:

  • Operation at stops and while moving (when the equipment is installed on a vehicle)
  • Joint operation of several direction finders (when communication equipment is available), e.g. as a part of Automated Spectrum Monitoring Systems (ARMADA, AREAL etc.)
  • To prevent overloading in complicated electromagnetic environment, digital radio receiver includes additional analogue path with 500 kHz bandwidth
  • The distance between antenna systems and operator's location can be up to 100 m
  • Power supply from portable electro generator, external AC mains or vehicle on-board DC.

Direction Finder Provides:

  • Search for emissions, their parameters evaluation, technical analysis and comparison with the database
  • Creation of databases, their extension and comparing of the recorded data with the references in the database
  • Field strength evaluation
  • Recording of the radio signal within wide bandwidth
  • Panoramic spectrum analysis within the entire operating frequency range or within separate intervals under complicated electromagnetic conditions, detection of changes in ambient electromagnetic conditions
  • Recording radio environment within a specified frequency range. This procedure can function within a long period and is based on amplitude/frequency/bearing/time coordinates, unit location and the absolute time at the time of saving
  • Single- and multi-channel direction finding of radio signals with any modulation types and spectrum width
  • Demodulated signals playback
  • Accumulation of data for further analysis in the post-processing mode, simultaneous recording of demodulated signals and their service parameters (frequency, time, signal level, etc.)
  • Displaying bearing to a radio emission source in electronic map
  • Check of frequency/time parameters and service information of base station of modern communication and data transmission systems (GSM, IS-95, cdma2000, EV-DO, UMTS, TETRA, DECT, LTE, Wi-Fi, DMR, APCO P25).
