UNIT Radar Systems (RADAR 2 & Tracking Dish)

The UNIT Radar Systems—comprising the RADAR 2 screens and the tracking dish in the UNIT radar facility—monitor an unidentified object's trajectory, including its 20 miles-per-second orbital speed, sudden trajectory shift, and precise atmospheric entry toward Dungeness. The tracking dish locks onto the object (later revealed as the Axos spaceship), exposing its artificial/organic design and Earth-bound course, while RADAR 2 relays critical data (bearing, velocity, path) to operators. The system tracks the object's variable mass and abrupt disappearance, triggering a high-stakes response from UNIT personnel (Benton, Yates, Chinn, Brigadier Lethbridge-Stewart) and the Doctor's urgent warning about uncontrolled warheads. The dish and screens work in tandem, with Radar 2 initially attributing anomalies to glitches before confirming the extraterrestrial threat.
