What is the role of a radar receiver in a Pulse Radar system?

In a Pulse Radar system, the radar receiver plays a crucial role in detecting and processing echoes from targets. When the radar transmits a pulse signal, that signal travels through the environment until it encounters an object. This object reflects some of the signal back toward the radar system. The radar receiver is responsible for capturing these echoes, which contain valuable information about the distance, speed, size, and other characteristics of the target.

Once the echoes are received, the radar receiver processes this information, often using various algorithms or signal processing techniques to extract meaningful data. This includes filtering out noise, determining the time it took for the echoes to return (which translates to distance), and in some systems, analyzing the frequency shift of the echoes to gauge the target's speed through the Doppler effect. The precise functioning of the radar receiver is essential for accurately identifying and tracking targets, making it a fundamental component of the overall pulse radar system.
