What is the primary function of radar systems?

The primary function of radar systems is to detect and track objects by emitting radio waves. Radar technology operates on the principle of sending out radio wave pulses and then receiving the echoes that bounce back from objects in their path. This process allows radar systems to identify the position, distance, speed, and direction of moving and stationary objects, making them invaluable for applications such as air traffic control, weather monitoring, and military surveillance.

The use of radio waves enables radar to operate effectively in various conditions, including darkness and adverse weather, unlike systems that rely on visible light or laser-based measurements. This versatility is a key reason radar plays such a significant role in various fields. The ability to detect and track provides critical data that support decision-making processes in real-time situations.
