The goal is to fill the multi-dimensional data space with additional information from acquisitions having different spatial or temporal baselines. Multi-baseline imaging opens the door for a new class of image products in spaceborne SAR. Well-known examples are across-track and along-track interferometry, which allow the measurement of surface topography, ground deformation, ocean currents as well as glacier movements. While across-track and along-track interferometry are well established techniques and have been widely used by current spaceborne SAR systems, PolinSAR, TomoSAR and HoloSAR are emerging techniques which are shaping the future development of spaceborne SAR. New mission concepts for multistatic SAR configurations with distributed and sparse arrays will pave the way for this development.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122114361","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}

A possible algorithm for processing of pulsar signals that consists of epoch-folding, matched filtering and detection is proposed and evaluated in this paper. The algorithm proposed is verified using the real experimental data obtained from the radio observatory Dwingeloo, the Netherland. The serious trouble in this study is that the total number of the input data within a repetition period is much more of the number of samples in a pulsar template taken from the EPN database. Therefore have been developed and evaluated two new algorithms for epoch-folding, which not only improve Signal-to-Noise Ratio of pulsar signals but as well reduce the number of samples of the output signals to the required number.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123529023","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}

Its ability to penetrate many non-polar dielectrics allows tomographic imaging of an object's 3D structure. The authors' previous work demonstrated the ability to produce 3D THz tomographic images of objects using a single data set collected in a 2D synthetic aperture configuration. This ability was recently expanded to allow imaging to within objects with curved boundaries by employing a split-step Fourier method to numerically back propagate the measured fields to the set of image planes that comprise the 3D tomographic image. This work presents new experimental results that demonstrate the split-step Fourier method's ability to correct for refraction and accurately quantify the thickness of a curved dielectric layer.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115370671","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}

Future sensor generations will be challenged by constantly demanding resolution requirements not only requested by consumer rating organizations, but also by very demanding needs to realize automated driving tasks. Facing these novel challenges results in perpetual increasing of resolution requirements to guarantee highly detailed and accurate information of the surrounding area of the vehicle. Due to the high resolution operation mode a plenitude of scattering points reflected by each physical object will flood the detection list. This paper copes with the clustering of all these reflections into appropriate groups in order to exploit the advantages of multidimensional object size estimation and object classification.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124919892","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}

Dictionary-based parameter estimation methods have developed rapidly. The dictionary construction is the key issue for the dictionary based method. A Time-domain dictionary (TD) for the ASC model parameter estimation is presented in this paper. Two-dimensional frequency domain responses of the ASC are produced and transformed into the time domain. Then the time domain responses are cut off and vectored. These vectored time-domain responses are amalgamated to form the TD. Compared with the traditional frequency-domain dictionary (FD), the TD is a matrix that is quite spare and can markedly reduce the data size of the dictionary. Finally, the performance of the TD has been analyzed in comparison with the FD. In addition, a parameter estimation example from a target's SAR data collected in an anechoic room is exhibited.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129647891","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}

Swelling operational costs along with potential RF spectrum licensing cost increases are driving ANSPs to consider innovative approaches for independent non-cooperative surveillance. PROVE, a two-year project conducted by NATS, Thales UK ATM and Roke Manor, investigated the capabilities offered by this technology. The project executed a number of trials exploring passive MSPSR performance in terms of coverage, probability of detection, accuracy and capabilities in the presence of wind-turbines. The results demonstrated that the technology can achieve accuracy levels to support 3NM separation, while providing a reasonable coverage and probability of detection. The results also indicated that such systems may have an inherent capability to suppress wind-turbine clutter. PROVE demonstrated that MSPSR technology, while not mature enough for operational service, has the potential to provide future independent non-cooperative surveillance whilst suppressing wind turbine clutter. Given the maturity level and demonstrated capabilities, MSPSR technology should continue to be developed and matured.","PeriodicalId":117775,"journal":{"name":"2015 16th International Radar Symposium (IRS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125442482","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}
