radar beam
Scanning energy pulse
A radar beam is the focused stream of radio waves transmitted by a radar system to detect objects.
The beam travels outward, bounces off aircraft, ships, or weather formations, and returns to reveal their location and movement.
The radar beam swept across the sky, tracking incoming flights.
