A modern radar can track a thousand targets by electronically bending light

Modern missile defense systems utilize gallium nitride technology to steer invisible beams of energy in microseconds, allowing a single radar to track over a thousand threats simultaneously without moving a single mechanical part.

Modern missile defense systems like the Golden Dome use advanced phased-array radars to monitor the skies with unprecedented precision. Instead of a rotating dish, these systems use thousands of tiny antenna elements that electronically shift the phase of electromagnetic waves. By precisely timing these shifts, the radar can 'bend' its beam in any direction in mere microseconds. This allows the system to scan a full 360 degrees and track more than 1,000 targets at ranges up to 3,000 kilometers.
