摘要

PROBLEM TO BE SOLVED: To provide a beam-forming network of active antennas having a sub array of expanding type, a space ship having such a network, a method of forming a beam, and a system including the space ship and at least one beacon-transmitting base.;SOLUTION: The network receives displacement information of relative positions between two panels. In order to make a received signal coherent, a received signal is reproduced taking the displacement information into consideration of.;COPYRIGHT: (C)2003,JPO
