东京大学和科比大学正在计划一个大型膜“Furoshiki卫星”延伸和大型相控阵射频传输的探空火箭实验。本文将介绍“风城卫星”的概念，其应用于相控阵天线，并使用小型探空火箭的微重力实验方案。东京大学一直在提出“Furoshiki Satellite”的想法，这是一个大的膜或网状结构，大小为1 km × 1 km，由卫星延伸，卫星保持其角落。膜或网状结构的姿态和形状由这些角卫星控制。作为Furoshiki Satellite的应用之一，大型相控阵天线可以由放置在大型网络结构的多个部分上的多个RF发射器来配置。精确控制射频发射机的位置和姿态是困难的，但采用“反向”方法，这种位置和姿态干扰的容忍度将大大放宽。这是未来大型太阳能卫星或大型天线的有前途的系统概念之一，因为可以在没有任何硬结构的情况下获得相当大的面积，并且重量不会很大程度上取决于尺寸[S。Motohashi，T. Nagamura，大尺度膜结构Furoshiki卫星-其概念和轨道/姿态动力学，第20届空间技术和科学国际研讨会论文集，1996年，第96-n-14页]。为了验证大网结构扩展和相控阵性能的可行性，计划使用日本ISAS/JAXA的探空火箭进行微重力实验。
University of Tokyo and Kobe University are planning a sounding rocket experiment of large membrane “Furoshiki Satellite” extension and large phased array RF transmission. The paper will describe the concept of “Furoshiki Satellite,” its application to phased array antenna, and the scenario of micro gravity experiment using a small sounding rocket. University of Tokyo has been proposing the idea of “Furoshiki Satellite,” a large membrane or a net structure, say 1km×1km in size, extended by satellites which hold its corners. The attitude and the shape of the membrane or net structure is controlled by these corner satellites. As one application of Furoshiki Satellite, a large phased array antenna can be configured by several RF transmitters placed on several parts of the large net structure. It is difficult to control the position and attitude of the RF transmitters precisely, but using the “retro-directive” method, the tolerance of such position and attitude disturbance will be relaxed by large. This is one of promising systems’ concept of the future large solar power satellite or large antenna, because quite a large area can be obtained without any hard structure, and the weight will not depend very much on the size [S. Motohashi, T. Nagamura, Large scaled membrane structure Furoshiki Satellite—its concept and orbital/attitude dynamics, in: Proceedings of 20th International Symposium on Space Technology and Science (ISTS), 1996, p. 96-n-14]. To demonstrate the feasibility of the extension of large net structure and phased array performance, micro-gravity experiment is planned using a sounding rocket of ISAS/JAXA, Japan.
