The method employs feeding transitions which allow to excite desired mode and measure parameters of transmission line with use of standard two-port vector network analyzer (VNA). Characteristic impedance is determined from easily measured propagation coefficient and static capacitance per unit length estimated from time-domain reflectometry (TDR) measurement. The results were checked against numerical data computed with use of the Spectral Domain Approach. Satisfactory degree of convergence between measured and numerical data has been achieved proving usefulness of worked out technique.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131763178","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 multiple reflect standards are assumed to be partly unknown and of the same type, e.g. offset terminations. Their reflection coefficients are modeled over frequency and identified during the calibration along with the VNA error terms. This novel technique is particularly useful for millimeter-wave VNA calibrations in which conventional transmission line standards and the TRL method become impractical. Experimental verification shows that the accuracy of our technique is very high and comparable with the one-port measurement accuracy of the multiline TRL method.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123852187","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 suggested approach is based on the extraction of phase-coupled harmonics from time-varying bispectrum estimates of transient sequences separated from the total radar backscattered signal by a sliding window. A coherent, homodyne, and continuous-wave radar has been employed for measuring multi-component, non-stationary, and nonlinear frequency modulated signals backscattered by moving objects. The experimental study underpinned with the theoretical assumptions of the suggested approach has demonstrated clean recovery of time-varying phase-coupled frequencies for test targets like a swinging metallic sphere or a walking human. The obtained time-frequency distributions of phase-coupled harmonics can be recommended as a new information feature in automatic radar target recognition systems.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116113050","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}

It includes seven RF stations distributed over a distance of 300 meters. Multiple RF devices at each station operating at frequencies in the range of 1 MHz to 2.8 GHz must be synchronized with sub picosecond accuracy. To fulfil the short and long term synchronization requirements a phase reference distribution system has been developed. It consists of a master oscillator (MO), signal distribution system and a fiber-optic phase monitoring link [3]. This paper describes the most important design issues of the MO. Phase noise and phase drift are addressed and the appropriate solutions used for minimizing those sources of errors are presented. Current status of the MO is described with measurement confirming the required performance.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114337296","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}
