A major application is coast surveillance. The recognition and the identification of maritime targets are important tasks. In this paper experimental results of ISAR images of maritime targets are reported. The data were captured with an LFMCW (linear frequency modulated continuous wave) millimeter-wave radar. High resolution ISAR images are obtained, since a great bandwidth (1 GHz) is transmitted. In ISAR the target motion can degrade the quality of the final images and motion compensation algorithms are necessary to improve the focus of these images. An autofocusing technique based on the shift-and-convolution algorithm is used to compensate the translational target motion and a two-phase algorithm (slant range rotation compensation (SRRC) and cross range rotation compensation (CRRC)) is used to correct the migration through resolution cells (MTRC) associated with the target rotation. The effectiveness of the focusing techniques is verified with simulated and real (maritime targets) radar data and compared with the standard range-Doppler algorithm (RDA)","PeriodicalId":299928,"journal":{"name":"MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130488168","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}

The collaborative work between the Jodrell Bank Observatory operated by the University of Manchester and the University of Birmingham has produced a range of filters operating in a number of observation bands between around 400 MHz and 8 GHz. Some of these filters have been tested in receivers and used for astronomy. This paper discusses the design of HTS filters, the mounting of the filters into a cooled receiver and the improved results obtained in astronomical observations. In addition, such a filter has been designed to operate in each element in a focal plane array, in this case a large number of filters are required in the array and miniaturization is a crucial criteria","PeriodicalId":299928,"journal":{"name":"MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114018722","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}

This is regulated by two market mechanisms: (i) the network constraint management, and (ii) the voltage control ancillary service. Constraint management is conducted by the SO, who asks generators to modify their outputs to solve power system voltage problems. On the other hand, the ancillary service consists of: (i) an annual auction where reactive regulation capacity VAR resources are agreed, and (ii) the scheduling and real-time operation of these VAR resources. Nowadays, only the first mechanism is fully implemented, while the ancillary service is partially established.
