The tactical 3D- Air-defense radar Master-T developed by the Thomson CSF Air Command and Control Systems Company (now Thales) is as a classical surveillance radar a member of an S band (IEEE designation) or E/F band (NATO designation) radar family including the fixed site variant (Master M) and a smaller multi-function radar (Master A).

The phased array antenna rotates with 6 r.p.m. and scans the airspace with pecil-beams up to an altitude to 100 kft. The phased array is composed of 35 linear arrays with 35 phase shifters. During the receiving time the radar uses the monopulse procedure.

The solid-state transmitter uses the pulse compression improving the range resolution. The radar data processing is fitted with a dedicated channel to track ballistical missiles beyond the normal cosecant squared antennas pattern up to a slant range of 350 kilometers and an elevation angle up to 70 degrees.

Two trucks with a load capacity of 10 tons are necessary for this fastly movable radar. The radar ist air-transportable with two C 130 aircrafts or Chinook- helicopters.
