Four different methods have been implemented to solve for the inverse problem, i.e., to get the atmospheric brightness from visibility samples on the ground. We have used a Fourier-based, Capon and Maximum Entropy (MaxEnt) methods. In addition, we have implemented a fitting technique where a brightness distribution, characterized by a number of anisotropic Gaussian blobs, is assumed. It is important to note that with our current configuration we can characterize up to six anisotropic Gaussian blobs. These four methods are compared using experimental and model data. For the experimental part, we have taken advantage of the good knowledge that we have on the mean position, orientation and aspect sensitivity of the equatorial electrojet (EEJ).ROJapplication/pdfengInstituto Geofísico del Perú, Radio Observatorio de Jicamarcainfo:eu-repo/semantics/openAccessAtmósferaLuminosidadRadar coherenteSistemas de imágeneshttp://purl.org/pe-repo/ocde/ford#1.05.01Three-dimensional coherent radar imaging: experimental and model comparison of techniquesinfo:eu-repo/semantics/otherreponame:IGP-Institucionalinstname:Instituto Geofísico del Perúinstacron:IGPORIGINALThree-Dimensional coherent radar imaging- experimental and model comparison of techniques.PDFapplication/pdf22854https://repositorio.igp.gob.pe/bitstreams/b1d35f97-922a-4841-87e2-308e40415ecd/downloadeb6b919c9df761f6c48c0543f51c647aMD51LICENSElicense.txttext/plain1748https://repositorio.igp.gob.pe/bitstreams/f77513a2-2497-4b20-8265-2cb872448ac8/download8a4605be74aa9ea9d79846c1fba20a33MD52THUMBNAILThree-Dimensional coherent radar imaging- experimental and model comparison of techniques.PDF.jpgThree-Dimensional coherent radar imaging- experimental and model comparison of techniques.PDF.jpgIM Thumbnailimage/jpeg132965https://repositorio.igp.gob.pe/bitstreams/7aaa88bc-6c43-4e1e-a19c-e5c2a11bf9dc/downloadbe1b504e8cf7bf719646995899bc2db0MD53TEXTThree-Dimensional coherent radar imaging- experimental and model comparison of techniques.PDF.txtThree-Dimensional coherent radar imaging- experimental and model comparison of techniques.PDF.txtExtracted texttext/plain2https://repositorio.igp.gob.pe/bitstreams/9bc872b8-eb62-4f69-a6de-af688edbc649/downloade1c06d85ae7b8b032bef47e42e4c08f9MD5420.500.12816/595oai:repositorio.igp.gob.pe:20.500.12816/5952024-10-12 22:18:51.809open.accesshttps://repositorio.igp.gob.peRepositorio Geofísico Nacionalbiblio@igp.gob.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
