AN/FPN-34
AN/FPN-34 was operating in the L-band frequency-diverse air traffic control radar, intended for use as a terminal area and en-route radar. The radar was fully remote controllable and could transmit its four video channels via microwave directional radio.
The antenna used a large parabolic reflector that provided a cosecant squared pattern that extended to altitudes of 60,000ft (≙ 18.2 km). Switching between circular and linear polarization was possible. Antenna directional information was transmitted by a two-channel servo system with a ratio of 1:36. The two transmitters used tunable magnetrons of type QK470A.
AN/FPN-34 was developed in the late 1950s.
