Which radar component demodulates echoes for display purposes?

The receiver is the radar component responsible for demodulating echoes for display purposes. When a radar system transmits a signal, the signal travels through the environment and reflects off various objects, returning as echoes to the radar system. The receiver's role is to capture these returned echoes and convert them into a form that can be processed and displayed.

Demodulation is the process by which the information carried by the returned radar waves is extracted. This involves transforming the received signals from their radio frequency to baseband signals, where they can be analyzed and converted into visual information for the display. This step is crucial because it allows operators to interpret the radar data, providing insights about the distance, speed, and direction of objects detected.

The other components mentioned play different roles in the radar system: the transmitter generates the radar signal, the amplifier boosts the signal strength to ensure it can be detected, and the filter is used to eliminate unwanted noise from the received signals. However, it is the receiver that specifically performs demodulation, making it essential for displaying the radar information.
