Abstract

Based on constructing planning of Space Solar Power Satellite (SSPS) in China, transmitting antenna aperture is about 200m in megawatt SSPS system with technological development in future. According to the constrained condition of transmitting and receiving antenna, with respect to contradiction beam collection efficiency and construction cost that are both associated with receiving antenna aperture, power density distribution in receiving antenna of different size is analyzed and studied. And high efficiency requirement of rectifier because of power density' distribution difference is emphasized. Simulation results show that reasonable size of receiving antenna in megawatt SSPS system is 5km, while only one type of diode and same rectifier are adopted in whole antenna area. This parameters should be supported systemic optimization for megawatt SSPS. Finally, feasible techniques suit for megawatt SSPS of lower power density is proposed.
