Radar Theory

Basic

• A basic radar system is split up into a transmitter, switch, antenna, receiver, data recorder, processor and output display.
• Everything starts with the transmitter as it transmits a high power pulse to a switch which then directs the pulse to be transmitted out an antenna.
• Just after the antenna is finished transmitting the pulse, the switch switches control to the receiver which allows the antenna to receive echoed signals.

• Once the signals are received the switch then transfers control back to the transmitter to transmit another signal.

• The switch may togle control between the transmitter and receiver as much as 1000 times per second
