Definitions

  • the invention is related to at least one movement mechanism capable of at least partial shifting of the phase shifter in an antenna used particularly in a radar system.
  • Radar is a device that detects distant objects, and their speed, bearing and distance, with the help of the reflection of radio waves.
  • electromagnetic signal pulses are sent through antennas and after the energy carried by the radio waves reaches the object, it returns by being reflected from the object, and these reflected signals are called echoes.
  • intensity, direction and return time of echo are very important. In line with these parameters, the properties of the detected object are determined.
