Abstract :
Aperture synthesis is an emerging technology for passive microwave remote sensing from space. It is an interferometric technique in which pairs of small antennas and signal processing are used to obtain the resolution of a single large antenna. The technique has been demonstrated successfully at L-band with the aircraft prototype, ESTAR; and proposals have been submitted to demonstrate this technology in space.
