Abstract	Solar power satellite (SPS) is paid attention to as a clean, inexhaustible large-scale base-load power supply, where carbon dioxide is not exhausted. In order to send power a receiving site correctly, the ground receiving site sends a pilot signal and the SPS sends power by a microwave to the arrival direction of the signal. Two technologies related to beam control are reviewed. A system which uses a spread spectrum pilot signal is introduced. An arrival direction is estimated from the pilot signal after despreading the SS modulation. This does not respond to fake or wrong signals and is more reliable under power transmission. A single frequency can be used for both monochromatic power transmission and a carrier of the pilot signal and the antennas are shared for both power transmission and pilot signal reception. Antenna radiation patterns are optimized for high transmission efficiency and low sidelobes under a uniformly excited array through a genetic algorithm. Radiation patterns directed to multiple directions can also be created.
