The first system, called SETHI, is presented in the first section. It has been developed according to the standard FAR25 applied to civil application. The main improvement compared to the previous ONERA airborne radar system RAMSES is that the antennas are located into two pods compatible with small aircrafts like the Falcon 20. This pod-based configuration allows the easy integration of any kind of payloads under the single certification of the pods by authorities. The second section describes the BUSARD concept, dedicated to UAV-like payloads. A special attention is set on its Ka-band radar payload. Finally, we describe the RAMSES NG project, with a new installation on board a Falcon 20 aircraft and we expose the latest X-band developments. The three systems are summarized on overview tables.","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116028292","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 main evolution of these systems, from a design point of view, have two origins, one being the Tactical Picture Compilation (TPC), the other being the extension of the warfare domain of weapon systems connected to MFR. As far as TPC is concerned, Long Range coverage and proximity of littoral, have been the major requirements impacting the design of naval MFR. This paper discusses the principal features of typical architecture for modern Naval Multi-Function RADAR, and how the requested new missions impact the design.","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129660194","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}

However, this method cannot measure a correct angle for multiple targets which cannot be distinguished by range, Doppler frequency and beam width. A method to simultaneously measure azimuths and elevations for only two targets was proposed, which requires a low computational load compared with other methods. However, the conventional method requires four receivers, therefore it is difficult to utilize it when there is a hard ware limitation. In this paper, we propose a method to measure azimuths and elevations for two targets using two receivers and time division system. We also show a verification of the proposed method by a numerical simulation and experimentation, though measured angles are restricted to azimuths or elevations. The results show that two targets angles can be measured by our proposed method using two receivers.","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126932263","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}

Each of these systems is dedicated to a particular task and the cooperation is reduced to a minimal exchange of information between them, so far. Major system performance enhancements are to be expected from close cooperations to each other sensors. The future co-operations can be ordered in four stages. The first three ones lead progressively to a multi-functions sensor. The last one is the deployment, on a given platform, of compact multi-functions sensors on a network basis. Another area of co-operation is the realization of R.F. functions that are currently provided by other devices using other antennas. A typical example is the implementation of data links using the Radar or the EWS.","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"65 4-5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120915265","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}

Access to high speed data converters enabling up and down conversion directly in the L Band and S Band removes the limit imposed by bandwidth scarcity and allows the design of flexible and simplified system architectures. Broadband ADC's (Analogue to Digital Converters) are key enabling components which open up new design opportunities for digital Receiver systems. In this regard, this paper describes a new 10bit 3GS/s ADC with 5 GHz Bandwidth, based on a 200 GHz SiGeC bipolar Technology, which enables the direct digitizing of 1GHz arbitrary broadband waveforms directly in the high IF region closer to the Antenna (L-Band or S-Band).","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130842029","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 multi-resolution property of WPT and the characteristic of good energy concentration on LFM signals in FRFT domain are combined together. At first, optimal wavelet tree is calculated using “minimum Shannon entropy” and threshold censored method is used to suppress sea clutter of different frequency bands. Then, take the absolute amplitude of signals after FRFT as test statistic and search for peaks in two dimensions with the threshold. Grading iterative method is used for parameter estimation with fast calculation speed and the shading problem between multiple targets is solved through “CLEAN” method. In the end, simulations with IPIX data indicate that the proposed algorithm has good performance of detecting low-observable moving targets in sea clutter.","PeriodicalId":125591,"journal":{"name":"2010 IEEE Radar Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127508524","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}
