【発明の名称】通信衛星アンテナのような電磁信号送信ネットワークにおける各種チャネルの振幅および位相の決定方法
Document Type and Number:
Japanese Patent JP2002517926
Kind Code:
A
Abstract:
Amplitudes and phases of different channels in an electromagnetic signal transmission network, whereof the sources are arranged in a triangular lattice, are determined by tiling the lattice with hexagons having six equal sides, the hexagonal tiles that are formed are distributed on the lattice such that two successive tiles along a direction in the lattice rectangular height equivalent to the triangular lattice are offset by an elementary step along the width direction. A Fourier transform is performed on the resulting tiles; directions are selected on the resulting new lattice corresponding to the transmission directions; an inverse Fourier transform is performed of the directions; and amplitude and phase coefficients to be applied to the transmission network different channels are deduced from the inverse Fourier transform.
