中文摘要	We propose a photonic beam-forming network scheme based on a broadband optical source (BS), double sideband suppressed carrier (DSB-SC) modulation, and a chirped,fiber grating (CFG). The principle and feasibility are proved by both theoretical analysis and experiments. In 20-32 GHz microwave band, experimental results show a good delay time consistency and the ratio of RF signal to noise met the practical application demands. The thne consistenc ' v errors ort smaller than 3 ps in 20-40GHz bond. Specially, compared with traditional double sideband (DSB) modulation scheme, in the proposed approach the dispersion-induced RF power degradation is effectively mitigated over 24 dB at 30 GHz, and the experimental results agree well with the theoretical ones.
