摘要：A space photovoltaic power generation system comprises a plurality of powersatellites (1) arranged in space, each of which converts electric energy, in which sunlight
has been photoelectric-converted, into a microwave, and transmite the microwave to anelectric power base (4). The space photovoltaic power generation system divides theplurality of power satellites (1) into a number of power satellte groups and adjusts theamount of phase adjustment to be made to a microwave which each of the plurality ofpower satellites (1) included in each power satellite group will transmit so that a pluralityof microwaves from the plurality of power satellites (1) included in each power satellitegroup are in phase with one another. The beamwidth of the plurality of microwaves canbe reduced without increasing the area of the aperture of a transmission antenna of eachof the plurality of power satellites (1). If the plurality of microwaves transmitted from theplurality of power satellites included in each power satellite group interfere with
microwaves transmitted from any other power satellite group, the beamwidth is reduced.To avoid the reduction in the beamwidth, each of the plurality of power satellites (1)included in each power satellite group modulates the phase-adjusted microwave so as togenerate an incoherent microwave so that the microwave does not interfere with othermicrowaves transmitted from any other power satellite group.
