The developed technology is based on shielded microstrip (S-MS) employing a standard monolithic microwave integrated circuit compatible process. The S-MS transmission media uses a 5-µm layer of benzocyclobutene (BCB) on shielded metalized ground plates avoiding any substrate coupling effects. An insertion loss of less than 3 dB/mm was achieved for frequencies up to 750 GHz. To prove the effectiveness of the technology, a variety of test structures, passive components and antennas have been design, fabricated and characterized. High Q performance was demonstrated making such technology a strong candidate for future THz-MIC technology for many applications such as radar, communications, imaging and sensing.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127194516","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 electromagnetic wave returning from a target vehicle can get reflected on those surfaces causing a non existing so-called ghost target. For driver assistance systems ghost targets can lead to false decisions and, therefore, they should be detected and avoided. In this paper a model for describing those ghost targets and a procedure to distinguish them from real targets using the orientation and the motion state of a vehicle is presented.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125851267","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}

This can be achieved using multistatic GNSS acquisitions with multiple satellites and a single receiver, and applying multilateration techniques. For an experimental verification, the target localisation concept was applied to practical maritime measurement conducted with GNSS-based radar test bed and bistatic ranges of one target for two different satellites successfully gained.

DVB-T2 has been improved in order to achieve a higher data rate and to allow more flexibility for different use cases. This leads to an increased computational effort. The basic concept for the pilot pattern is maintained so that for both standards additional peaks are generated in the ambiguity function. This problem can be fixed with the same filtering approach. Full reconstruction of the OFDM symbols isn't possible on all sub-carriers for DVB-T2 for several reasons, e.g. peak power canceling algorithm. A special challenge respresents also the MISO-Mode (Multiple Input Single Output), where a single frequency network can be split into transmitter groups so that different, but similar signals are broadcasted. For normal broadcast receivers the interference of two transmitters with similar power can be removed in this mode, but for passive radar processing the superposition according to the ambiguity function and the cross-coupling functions are of importance so that the separation of target signals from line-of-sight-components and clutter is more involved.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116870152","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 first is multipath detection that detects appearing and disappearing targets automatically, while one target may produce s tracks for s propagation paths. The second is multipath tracking that calculates the target-to-measurement-to-path assignment matrices to estimate target states, which is computationally intractable due to the combinatorial explosions. A joint multipath target detection and tracking method is proposed based on random sample consensus (RANSAC). Using the iterative hypothesize-and-test framework of RANSAC, the close loop between identification of target-to-measurement-to-path and estimation of target states is established, which is conducive to improving the tracking performance by utilizing multipath measurements. Numerical simulations demonstrate the effectiveness of the proposed method.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127765514","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 rapid progress in performance of highly integrated electronic components (digital, analogue or mixed-signal) has enabled several trends such as miniaturization and cost reduction of sensor devices, a migration to higher frequencies in the millimeter and Terahertz domain, or real-time execution of mathematically complex signal and array processing methods. On the other hand, the electromagnetic spectrum is a scarce and strongly controlled resource that is proving to be increasingly valuable. Radar devices must be able to handle more signal bandwidth with greater receiver sensitivity and are competing with an increasing number of other systems for communication, navigation, or wireless connectivity. In this environment, it is necessary to understand the different requirements and find strategies of a co-existence without performance degradation.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125878716","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}
