A pattern measurement method of SPS test satellite with phased array antenna

Abstract

  A demonstration experiment using a small satellite is planned to realize space solar power system (SPS). In this experiment, accurate evaluation of the beam shape transmitted from the satellite is needed. So, the beam shape had been reproduced and evaluated as a parabola antenna. In this paper, the antenna changed to a phased array antenna for more realistic situation. Then, a guideline for base station placement was shown, and the pattern was reconstructed by the two-dimensional minimum square method to confirm its effectivity. In addition, the orbit passing through Usuda as well as Katsuura were shown.
