  • The diagram shows basic radar system which consist of transmitter receiver and antenna which act as both transmitting and receiving antenna.
  • The main function of the duplexer is to connect the transmitter to these antenna, when the pulses are to transmitted and connect the antenna to these receivers, when echo –pulses are received.
  • Pulse modulated Magnetrons, Klystrons, and Travelling Wave tubes (TWT) or Crossed-field amplifier (CFA) are used as transmitter output tubes. In the receiver for first stages usually a diode mixer is used. The antenna generally uses a parabolic reflector.
  • Antenna can scan continuously the scanning speed of antenna is mechanically is higher part, it issmall in comparison with the time taken by pulses to return from.
