Previous papers have shown computational simplifications which reduce the number of computations for designing sequences with good autocorrelation and cross-correlation properties to O(N logN). In this paper, we present derivations and algorithms for designing sequences with specific autocorrelation, cross-correlation, and spectral properties, and show how sequences can be designed to also have these properties be good simultaneously. Sequences with autocorrelation and cross-correlation constraints meet the known bounds. Adding spectral constraints degrades the correlation properties of the designed sequences, and we quantify those effects by example.","PeriodicalId":185932,"journal":{"name":"2016 IEEE Radar Conference (RadarConf)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132170710","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 clutter covariances are assumed to be random and different from one transmit/receive pair to another with a priori knowledge about the environment. A two-step strategy is employed to design adaptive detector. Firstly, we obtain the generalized likelihood ratio test (GLRT) detector by assuming the known covariance matrices. Then, we derive the maximum a posteriori (MAP) estimator of the matrices by exploiting the Bayesian technique, and replace the given covariance matrices in the obtained GLRT detector with MAP estimates. Finally, we evaluate the proposed adaptive Bayesian detector via numerical simulations.","PeriodicalId":185932,"journal":{"name":"2016 IEEE Radar Conference (RadarConf)","volume":" 99","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113948561","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}

Historically, most fielded ESA systems have been comprised of highly tailored, application-specific layers.

The approach can account for multiple-scattering and multi-path information in the data, and results in quantitative information about the subsurface. The method is now well studied for seismic imaging, as well as for GPR imaging in 2D. However, taking a 2D imaging approach limits the applicability and accuracy of FWI whenever significant 3D effects have been observed, such as out-of-plane scattering. We present a theoretical approach to FWI for GPR in 3D, which utilises Total Variation regularisation and a novel Hessian approximation, as well as a coupled finite-element boundary-integral solver for Maxwell's equations to simulate the GPR forward problem. We test the algorithm with a numerical experiment into the reconstruction of a domain containing nearby targets buried in a cluttered, stochastically varying, background soil medium.","PeriodicalId":185932,"journal":{"name":"2016 IEEE Radar Conference (RadarConf)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128786711","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 traditional segmentation in driving, manoeuvering and parking tasks vanishes at the driver less stage.

Hence, fast situational up-date, motion prediction of all kind of dynamic objects, object dimension, ego-motion estimation, (self)-localisation and more semantic/classification information, which allows to put static and dynamic world into correlation/context with each other is mandatory.

Compressed sensing based two dimensional beamforming enables imaging of humans with sub-Nyquist number of elements in the radar aperture. In this work, we apply this imaging technique to humans in through-wall scenarios in indoor environments. Walls are complex propagation environments that introduce refraction, attenuation, ringing and multipath to the radar signal. In this work, we quantitatively analyze the impact of inhomogeneous walls on the direction-of-arrival estimation with array processing. Next, we examine the impact of wall clutter on compressed sensing based radar imaging. The radar data scattered by humans moving behind walls is simulated by hybridizing wall propagation models, derived through computational electromagnetic techniques, and electromagnetic primitive based models of moving humans.","PeriodicalId":185932,"journal":{"name":"2016 IEEE Radar Conference (RadarConf)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116682511","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 article we present an application of CS and sparse reconstruction in a radar setup to form range-Doppler maps. We characterize a radar system where instead of transmitting a train of pulses the pulse transmission occurs in a sparse manner. An array based radar may thus for example alternate beams between two or more angles within the same processing interval applying the entire array. We show that gaps in data can very adequately be filled in by sparse reconstruction which can also be used to extrapolate additional values. Comprehensive simulations covering various scenarios, including sea clutter conditions, are used to demonstrate the effectiveness of the scheme.","PeriodicalId":185932,"journal":{"name":"2016 IEEE Radar Conference (RadarConf)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115202895","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}
