Which component in radar blocks amplifies and processes received echo signals?

The component in radar that amplifies and processes received echo signals is the receiver. In radar systems, once transmitted waves hit an object and produce echoes, these signals need to be captured and analyzed to extract useful information. The receiver fulfills this role by amplifying the weak echo signals, which may have been significantly diminished due to distance and atmospheric conditions.

Additionally, the receiver processes these signals to filter out noise and enhance the relevant data, allowing for accurate detection and measurement of the target's location, speed, and other characteristics. This processing is critical for determining the position of objects and making tactical decisions based on radar data.

The transmitter is responsible for sending out the radar signals, while the synchronizer ensures that the transmitted and received signals are timed correctly. The modulator generates the waveform for the transmitted signal. While these components play vital roles in the overall functioning of a radar system, it is the receiver that specifically amplifies and processes the echo signals received back from targets.
