AN/FPS-33
AN/FPS-33 (alias HiPAR) was an operating in L-Band High-Power Aquisition Radar for the Nike Hercules air defence missile complex.
Initially it was a fixed installation radar using a cosecant squared antenna. The reflector dimensions were 20.6 × 43.0 ft. (6.3 × 13.11 m). It was usually installed on a tower and was covered with a fixed radome. Later versions became a relocatable radar, which was mounted on 5 flat trailers. This was named AN/MPQ-44. It uses a retractable folding antenna structure (General electrics' “Project Butterfly”) and formed a fan beam pattern. The transmitter was equipped with a klystron as power amplifier.
