This photo shows both the Zeus Discrimination Radar (DR), on the right, inside the two clutter fences, and the Target Tracking Radar (TTR) on the left. Just out of the picture to the left (not shown) is the Missile Control Building (MCB). The two fences around the DR were normally referred to as "clutter" fences, meaning they prevented ground returns, or ground clutter, from being received by the radar. They were also sometimes referred to as "beam forming" fences. You will notice that the automobiles are parked at the far left end of the parking lot, away from the parking lot entrance. The raised, dark feature leading from the outer fence at the left end of the parking lot, through both fences, and to the left side of the building was the personnel entrance/exit tunnel. Thus, cars parked near the entrance. At some time after this photo was taken, a small section of clutter fence was added in front of the TTR as well. If you look closely, you can see the launcher area in the photo almost straight above the TTR.

     After the Zeus program ended, these two radars were used as a part of a network of radars located at various locations at White Sands to provide re-entry signature information for the Athena program until the early 1970s. At that time, the antennae were removed, along with all the radar equipment inside. The TTR building was, and still is, used by the Government Test managers and project engineers for the Patriot System. The DR has been converted into an anechoic chamber facility for testing various systems/items for vulnerability to RF signals and the signals they may emit which would interfere with other equipment.
