radar antenna
Rotating detection dish
A radar antenna is the component of a radar system that transmits radio waves and receives their echoes after they bounce off objects.
The antenna's shape and movement determine the radar's range and coverage area.
Rotating antennas scan continuously, while phased-array antennas steer beams electronically without moving parts.
