Digital beamforming synthetic aperture radar

WebA promising candidate for such a new radar imaging technique is digital beamforming on receive where the receiving antenna is split into multiple sub-apertures (cf. Figure 1). In contrast to analog beamforming, the received signals from each sub-aperture element are separately amplified, down-converted, and digitized. WebSynthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving …
