thumb|right|Radar components A radar's components are: A transmitter that generates the radio signal with an oscillator such as a klystron or a magnetron and controls its duration by a modulator. A waveguide that links the transmitter and the antenna. A duplexer that serves as a switch between the antenna and the transmitter or the receiver for the signal when the antenna is used in both situations. A receiver. Knowing the shape of the desired received signal (a pulse), an optimal receiver can be designed using a matched filter. A display processor to produce signals for human readable output devices. An electronic section that controls all those devices and the antenna to perform the radar scan ordered by software. A link to end user devices and displays.
