WebDec 15, 2024 · Partial aperture imaging system (PAIS) is a recently developed concept in which the traditional disc-shaped aperture is replaced by an aperture with a much smaller area and yet its imaging... WebA synthetic aperture radar (SAR) is an active sensor that first transmits microwave signals and then receives back the signals that are returned, or backscattered, from the Earth’s surface. The instrument measures distances between the sensor and the point on the Earth’s surface where the signal is backscattered.
