Master-T
The Master-T is a tactical 3D air-defense radar, part of a family of S-band (IEEE designation) or E/F-band (NATO designation) radars developed by Thomson CSF Air Command and Control Systems Company (now Thales). This family includes the Master M fixed-site variant and the smaller Master A multi-function radar. The Master-T's phased array antenna rotates at 6 revolutions per minute (10 seconds per rotation), scanning the airspace with pencil beams up to an altitude of 100,000 feet and an instrumented range of 240 nautical miles. The antenna comprises 35 linear arrays, each with 35 phase shifters, and employs a monopulse procedure during reception. Its solid-state transmitter utilizes pulse compression, enhancing range resolution to 45 feet. The radar's data processing includes a dedicated channel for tracking ballistic missiles, extending beyond the normal cosecant squared antenna pattern to a slant range of 350 kilometers and an elevation angle of up to 70 degrees. The Master-T is a rapidly deployable system, requiring two 10-ton trucks for transport and air-transportable by two C-130 aircraft or Chinook helicopters.
