Abstract:

Some important space power satellite retro-directive microwave beam steering studies are introduced. The primary scheme and parameters of the microwave power transmission (MPT) for the solar power satelliteare are proposed and the simulation model of the MPT and retrodirective beam steering is built. Based on the simulation model, the influences of various error factors on the transmission efficiency, including microwave feeding phase, frequency and attitude of sub-arrays, are analyzed. The conclusions can provide important references for the researches on MPT system and technologies in the future.

Key words: Solar power satellite, Microwave power transmission, Retrodirective beam, Beam steering
