Direction Finder Provides:

• Single- and multi-channel direction finding of radio signals with any modulation types and spectrum width
• Search and detection of radio emission, measurement of their parameters
• Recording of radio signals
• 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, direction finder location and the absolute time at the time of saving
• Accumulation of data for further analysis in the postprocessing mode
• Creation of databases, their extension and comparing of the recorded data with the references in the database
• Displaying the emitter bearing and localization of the emitter on the electronic map

Antenna system of the direction finder comprises two arrays: basic and additional ones. The basic array consists of nine flat antenna elements mounted on foldable cross-arms. The additional array extends frequency range up to 3 GHz. It comprises seven antenna elements installed inside protective radome. Antenna system contains integrated satellite navigation module, which provides for finding orientation and coordinates of antenna system.
