The performance characteristics of the key components of photonic beamformer based on DWDM technology and fiber chromatic dispersion are examined and specified. A five channel beamformer prototype is built using the components available on the market of fiber-optic analog communication links and tentatively investigated. 5-element microwave linear array antenna far-field patterns in 6–18 GHz frequency range have been measured which demonstrated the designed model beamforming features for antenna pattern shifted up to 40°. The results of experimental testing agree with the calculated estimates.","PeriodicalId":321624,"journal":{"name":"2017 XI International Conference on Antenna Theory and Techniques (ICATT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124481589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their arrangement and a structure of a system of the channels, either in the presence of Taylor (or Hamming) weighting of output signals of the modules (or elements) or in its absence, for effective extracting of signals embedded in noise jamming is studied.
