PROBLEM TO BE SOLVED: To achieve real-type delay type light control array antenna, that is capable of transmission/reception where the number of wavelength-variable light sources is constant, regardless of the number of radiation elements and where reception multibeams can be formed. SOLUTION: A real-time delay taper 19 required for beam scanning is formed by the amount of real-time delay by a CFG (chirped fiber grating) 16, according to the wavelength of light waves from the wavelength-variable light source 9 (in a reception system, wavelengths are mutliplexed). Then, the light wave of each wavelength is wave-demultiplexed by a light-branching filter 12, to obtain a reception RF signal. |
