During the last six years (January 2005 to 2011) Cassini has performed 71 Titan's fly-bys and several observations have been collected in Altimetry mode. These profiles have shown Titan's surface complexity. Along track profile resolution can be improved by processing data in a coherent approach. This paper describes an advanced processing applied to the raw Altimetric Cassini radar data (LBDR, Long Burst Data Record). The processing is based on the well known Doppler/Delay algorithm. Results show an improvement respect to the existing ABDR (Altimeter Burst Data Record) products in terms of along track resolution and SNR.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114808074","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}

As a basic element of the matrix, the previously designed and measured 3.3-dB directional coupler has been used. Two different realizations of a 4 × 4 Butler matrix are considered, i.e. a network consisting of tapered-line couplers and a Schiffman phase shifter, and a network in which the appropriate phase characteristics have been ensured by substituting one of the 0/180° directional couplers by a 3-dB/90° directional coupler. In this solution, the needed coupler has been designed as a 5-section symmetrical coupled-line coupler in which the tightly coupled section is designed with the use of tapered-coupled-lines. The proposed technique allowed for achieving very good amplitude characteristics of the designed directional coupler due to the fact that the large discontinuity between coupled-lines having different coupling coefficients is avoided. The operational bandwidth of the presented 4 × 4 Butler matrices exceeds two frequency octaves.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134294355","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 designed Butler matrix utilizes the previously developed 5-section coupled-line symmetrical 3-dB/90° directional coupler compensated with the use of several tuning capacitances as a basic element. The broadband 45° phase shifters have been realized with the use of a tandem connection of two the same couplers and two 2-section Schiffman C-sections. The influence of the coupler's compensation on the differential phase characteristics of the 4 × 4 Butler matrix is presented, and it is shown that the applied compensation deteriorates differential phase characteristics of the designed Butler matrix. To overcome this problem a method for improving these characteristics is proposed in which an appropriate change to the middle network significantly improves differential phase characteristics of the entire Butler matrix.

The microwave beamforming networks are intended for automotive communications beam scanning electronically steered arrays. Although the frequency range likely to be allocated to such systems is 63 GHz, where the short transmission range allows multiple frequency re-use, the planar beamforming networks are frequency scaled models to verify the concept. The objective of this investigation is to develop microwave beamforming networks suitable for a use in inter-vehicle (IVC) and roadside-to-vehicle (RVC) automotive communications electronically steered arrays. The steerable microwave beamforming networks demonstrate appropriateness to develop well-established designs for systems that can be used in automotive communications beam scanning electronically steered array and vehicular telematics.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126109584","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}
