Synthetic Aperture Radar (SAR) Imaging

Fly a satellite along its orbit and coherently combine radar pulses into a synthetic antenna aperture. Compare the blurry image a small real radar antenna alone can form against the sharp image built by combining many pulses along the flight track.

A satellite's real radar antenna is small, so it alone forms a wide, blurry ground image. Switch to synthetic aperture mode and fly the satellite along a flight-path segment: every pulse fired along the way is coherently combined into a much larger virtual antenna, and the reconstructed image sharpens live as the synthetic aperture grows. Adjust real antenna size and flight-path length to see which one actually drives resolution.

⚙ Under the hood

Fly a satellite along its orbit and coherently combine many radar pulses into a synthetic antenna aperture. Compare the blurry image a small real radar antenna forms alone against the sharp image built by combining pulses along the flight track, with a live resolution readout.
