The EISCAT High Power HF Radar Capability

The EISCAT HF facility or ionospheric heater near Tromso, Norway, has recently been upgraded with the capability to function as a radar. One of the antenna arrays has been converted for receiving use, covering the frequency range 5.5-8 MHz. The transmitters now have direct digital synthesizers and are controlled by the same hardware and software systems used by the other EISCAT radars. With the new two-channel HF receiver the facility is capable of operating simultaneously as a heater and a HF radar.
