The choice of calibration method is closely related to the ambient environment of the radar station. This paper reports a calibration measurement of the UHF-band shore-based radar with active radar calibrator (ARC) on a fishing boat. It was found that multipath propagation effect due to the sea surface could not be eliminated as due to the ground. Based on the analysis of multi-path model, our experiment solved the problem of multi-path propagation better, and the calibration precision is controlled at 2dB.","PeriodicalId":297368,"journal":{"name":"2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121312254","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}

Then, the long-period scrambling code and source information will be estimated by the proposed ICA and PLL algorithm.

The proposed antenna can not only realize a wide differential-mode (DM) impedance bandwidth covering from 3.8 to 9.5 GHz, but achieve a high and wideband common-mode (CM) suppression by employing the balanced stepped-impedance microstrip-slotline transition structure. Besides, the DM passband is independent from the CM response, simplifying the design procedure significantly. In addition, a sharp DM notched band at 5.8 GHz is generated by adding one pair of quarter-wavelength short-circuited stubs adjacent to the microstrip line symmetrically. In order to illustrate the effectiveness of the design, one prototype of the antenna is designed, fabricated, and measured.
