Ground-based radar is a technology that uses radio waves to detect and track objects on or near the Earth's surface. It emits radio signals that bounce off objects, returning to the radar system, which then analyzes the signals to determine the object's distance, speed, and direction. This technology is commonly used in various applications, including weather monitoring, air traffic control, and military surveillance. The radar system consists of a transmitter, receiver, and antenna. Ground-based radar can operate in different frequency bands, allowing it to detect various types of objects, such as aircraft, vehicles, and even precipitation. Its effectiveness makes it a vital tool for ensuring safety and security in many fields, including aviation, meteorology, and defense.
