| Abstract(in English) | The contracted research project by "R&D on dynamic beam control technique for next generation mobile communication satellite" is on-going. The project is a collaborative project with Softbank Corporation and sponsored by Ministry of Internal Affairs and Communication of Japan. For large deployable antenna, change of surface shape in orbit is strong concern for stable service because the structure and mechanism to maintain the shape of reflector is complex and may have a sensitivity to external environment, especially to thermal environment. Deformation of parabola reflector will provide the change of pointing direction and antenna pattern and may cause deterioration of performance of communication service. If we can measure the shape of reflector in enough precision in orbit, compensation of antenna pattern with excitation amplitude and excitation phase optimized to deformed reflector surface. In this report, the feasibility of beam compensation due to optimization of phased array excitation to deformed reflector surface measured in orbit. |
