How Israel's Radar "Sees" 100 Miles Without Moving | Grand Structures

A warhead is small, traveling at extreme speed, and more than a hundred miles away. The radar echo that bounces back is fainter than a whisper across a crowded stadium. So how does the radar that catches it have zero moving parts? In this documentary, we break down the brutal physics and engineering of Active Electronically Scanned Array (AESA) radar systems, like the ELM-2084 used in Israel's Iron Dome. Discover how engineers use phase shifting to steer radio waves in microseconds without turning a physical dish, how the inverse fourth-power law punishes long-range detection, and why replacing one massive transmitter with thousands of tiny radar modules completely changed modern air defense.
