Abstract (en)
[origin: WO2005119842A1] The invention relates to a device for forming beams upon reception for an antenna having radiating elements. The device comprises at least: N optical sources (2) of respective wavelengths (lambda1, ...lambdaN), one optical source being assigned to a radiating element (11) in such a manner that a carrier of the optical wave is frequency modulated by the microwave received by the radiating element, and; an optical multiplexer (3) of which the transmission windows (32) correspond to the wavelengths (lambda1, ...lambdaN) and receive, at the entry, N optical waves, the output of the multiplexer being coupled to m optical media (6) each having a given chromatic dispersion, each optical medium being connected to an opto-microwave converter (7), the microwave at the output of a converter (7) entering a receiving path (V1, ..Vj...Vm), the direction of the emission beam of a path Vj being a function of the path in the optical medium and of the chromatic dispersion of the optical medium The invention is particularly used for an electronic scanning antenna for simultaneously creating a number of beams in the receiving pattern.
