The NLTL is based on parallel-plate ferroelectric (FE) capacitors. Figure of merit defined as the relative change of the reciprocal steepness of the wave front at NLTL input and output is suggested to characterize the NLTL efficiency. Formulas allowing the calculation of figure of merit for nonuniform ferroelectric-based NLTL are derived. The designed NLTL demonstrates three times increasing of front steepness for input rectangular video pulse of 1.5 ns front duration and 40 V amplitude.","PeriodicalId":181361,"journal":{"name":"2008 European Radar Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123353255","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}

In this contribution a 77-GHz frequency modulated continuous wave (FMCW) radar prototype is presented. The prototype is based on highly modular building blocks for both, the hardware as well as the software. This modular design offers an incredible flexibility for testing different components. The resolvability of multi target scenarios by a Kalman tracking filter is supported by using ramp sequences where each chirp has a different ramp slope. Measurements with the FMCW radar sensor are carried out in an automotive environment.","PeriodicalId":181361,"journal":{"name":"2008 European Radar Conference","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124589130","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 advantage of using MIMO array is that the number of elements can be reduced and the element spacing can be sparser than that of SIMO array, while the performance will be almost the same. Particle swarm optimization (PSO) method is used to determine the optimum antenna array topologies for different scenarios that can provide sufficient cross-range resolution and an acceptable mainlobe to side lobe level. The results demonstrated that by properly design the fitness function, we can trade off the cross-range resolution and mainlobe to sidelobe ratio and find proper array topologies for different scenarios.","PeriodicalId":181361,"journal":{"name":"2008 European Radar Conference","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127193612","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}

Efficient use of array technology and the need for radar solutions for various airborne platforms, manned and unmanned, leads to the design of scalable radar systems. The design and realisation of such a system is described. At the core of the design is a new generation of transmit-receive modules, developed and used also for naval radar systems. The radar architecture is largely based on the miniSAR system, which is close to completion. Design aspects are discussed for various envisaged versions of the scalable radar.","PeriodicalId":181361,"journal":{"name":"2008 European Radar Conference","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122757923","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}
