3-D radar

3-D radar is a type of radar technology that measures not only the range and angular direction of a target but also its elevation angle. This provides a three-dimensional picture of the airspace, unlike traditional radar systems that typically present a two-dimensional display.

Radar works by transmitting electromagnetic energy and analyzing the reflected echoes. The time it takes for the echo to return determines the target's range, while the antenna's direction indicates its angular position. 3-D radar systems often use phased-array antennas, which can electronically steer the beam rapidly and efficiently, allowing for quick updates on target locations and the ability to track multiple targets simultaneously. This advanced capability is crucial for applications like air defense systems.12
