Precision Approach Radar AN/FPN-36

The so-called “Quad- radar” is a highly mobile, air-transportable ground control approach radar and was designed for a precision approach under bad weather conditions. The approaching aircraft and the course & glide slope was seen on a Beta-scan scope.

In Germany this older radar was replaced by the PAR-80 radar.
