| Abstract(in English) | The stratospheric platform is expected for the use as a wireless base station at the altitude of about 20 km. Airships or solar-powered aircrafts are the candidate vehicles for the platform. It is known that the dimension of those vehicles is relatively as large as 35 m to 200 m, because they need to be operated under extremely low air pressure. By using the benefit from this, a large aperture array antenna will be constructed on the large bottom surface in order to obtain a high resolution in radiolocation systems. However, since such vehicles basically have flexible structure, calibration of the position of array antenna elements, as well as that of amplitude and phase imbalances, is inevitable. This paper proposes a system that estimates the location of radio sources on the ground by the large-aperture array antenna mounted on the vehicle with a flexible structure located at the altitude of 20 km and discusses on a calibration method for the location error of antenna elements. |
