AN/FPN-33
AN/FPN-33 was an X-band ground controlled precise approach radar that utilizes two prime-fed parabolic reflector antennas (azimuth and elevation) with an antenna gain of 39 dB, and two modes of operation (surveillance and tracking/precision approach).
It is the predecessor of the AN/FPN-36 which was fitted with an MTI then. The technical data were nearly the same, except for the much higher pulse power (and the higher maximum range) of the successor.
