This is one of the tracking radars. There is no real external difference between the:
The radars were bore sighted using a local (few hundred feet away) mast with radar

- Missile Tracking Radar - used to track the responding beacon (transponder) in
The radars used the "X" band, about 9,000 megahertz to 9,500 megahertz,
(3 centimeter wavelength).
