Radar is a system that sends out radio waves and listens for the echoes that bounce back. From that returning signal, it can estimate where something is, how far away it is, whether it is moving, and sometimes what kind of object it may be.</p> <p>The word <code>radar</code> comes from <strong>Radio Detection and Ranging</strong>, but modern radar does much more than simple detection. It can track aircraft, map rainfall, watch sea traffic, help cars avoid collisions, and build images of the Earth from space. This guide explains the idea in plain language so a beginner can understand the basics without getting lost in textbook detail.</p>
