星链终端相控阵波束成形

Starlink user terminals contain hundreds of tiny antennas arranged in a flat grid.
Each antenna emits radio waves with precisely controlled timing delays and phases.
By adjusting these phase shifts, the terminal steers a focused beam toward satellites.
This electronic steering works instantly, unlike mechanical dishes that must rotate slowly.
Phased arrays allow one terminal to track multiple satellites across the sky simultaneously.
They also adapt rapidly to signal blockage from trees or buildings in real time.
The system uses software-defined beamforming to optimize bandwidth and reduce interference.
Engineers test beam patterns using anechoic chambers before mass production begins.
This technology enables global broadband access even in remote mountainous regions.
Future versions may integrate AI to predict satellite positions and pre-adjust beams.
