SCANNING OPERATIONS FOR COLOCATED SATELLITE ANTENNAS

Methods, systems, and devices for scanning operations for co-located satellite antennas are described. For instance, a set of co-located satellite antennas may transmit a set of component transmit signals to form a beam, where a first line segment at a boundary of the beam is tangential to a first s...

Zusammenfassung:	Methods, systems, and devices for scanning operations for co-located satellite antennas are described. For instance, a set of co-located satellite antennas may transmit a set of component transmit signals to form a beam, where a first line segment at a boundary of the beam is tangential to a first sphere having a surface that encompasses Earth, where a location on the first line segment tangential to the surface of the first sphere is above a surface of the Earth by a threshold altitude. The set of co-located satellite antennas may receive a set of component receive signals including reflected energy of the beam. A central processor may apply a set of beamforming coefficients to the set of component receive signals to obtain a receive beam signal and may process the receive beam signal to obtain a signature associated with an object within a limb of the Earth.
