The automatic direction finder (ADF) DF 2000 is intended for the bearing of aircraft (during the operation of on-board radiostation transmitter) via 2—16 frequency channels (depends on a delivered conguration).
The ADF provides bearing of AM-modulated VHF signals using a phase method. The ADF utilizes electric switching of array vibrators (adcock antenna), which causes the rotation of one vibrator. The ADF consists of: processing rack, antenna system, antenna with a test generator, remote control and monitoring equipment, and a shelter with a life-support system.
