In a method for selecting a transmission targetterminal in a zero-forcing beamforming algorithm, information about a channel capacity of each terminal is received from all K terminals.
With computer terminal, optic system and software, the outdoor experiments are carried out aiming at distant target, and the image are processed by nonuniformity correction etc.
The guidance method satisfies terminal angular constraint as reentry vehicle hitting target, but also ensures minimum loss of maneuvering velocity for reentry vehicle.
