WebThe works most closely related to this paper are the synthetic aperture holographic setup proposed by Tippie et al. and the optical synthetic aperture approach of Beck et al. . Tippie et al. experimentally demonstrated synthetic aperture off-axis holographic capture of diffuse objects at a large standoff distance. Our approach can be ... 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.
