Such configurations allow -80% and -84% sample, respectively, of the total visibility plane that can be obtained using one quarter (= 16 modules) of the Jicamarca antenna. Measurements are made in the lower atmosphere (3-22 km) and upper atmosphere (65-80 km). We follow closely the theoretical development presented by Woodman, 1997 (Radio Sci., 32, 2373-2391). Different practical considerations are applied to both cases; for example, near-field effects are removed linearly in the lower-atmospheric measurements in order to get a focus image. In addition, we have implemented different algorithms to sol ve for the inverse problem, i.e., to obtained the atmospheric brightness distribution. As a first approach to the inverse problem, we have assumed a brightness distribution characterized by two Gaussian blobs. Each Gaussian blob consists of six parameters: angular positions (2), major and minor axis, angle of rotation, and relative intensity. Finally, we evaluate the gain obtained using our scheme as compared to the classical three non-collinear spaced antenna configuration.ROJapplication/pdfengInstituto Geofísico del Perú, Radio Observatorio de Jicamarcainfo:eu-repo/semantics/openAccessImágenes tridimensionalesRadio Observatorio de JicamarcaRadar coherenteAntenas (Electrónica)http://purl.org/pe-repo/ocde/ford#1.05.01Three-dimensional coherent radar imaging: lessons from the Jicamarca MST experimentsinfo:eu-repo/semantics/otherreponame:IGP-Institucionalinstname:Instituto Geofísico del Perúinstacron:IGPORIGINALThree-Dimensional coherent radar imaging- Lessons from the Jicamarca MST experiments.PDFapplication/pdf8568https://repositorio.igp.gob.pe/bitstreams/0ce6c9de-ccee-456a-9ba0-53a737d50195/download66520d918120de35698c4964520fa7abMD51LICENSElicense.txttext/plain1748https://repositorio.igp.gob.pe/bitstreams/9d518526-151c-41a6-871c-a2aba6ccdc7e/download8a4605be74aa9ea9d79846c1fba20a33MD52THUMBNAILThree-Dimensional coherent radar imaging- Lessons from the Jicamarca MST experiments.PDF.jpgThree-Dimensional coherent radar imaging- Lessons from the Jicamarca MST experiments.PDF.jpgIM Thumbnailimage/jpeg102711https://repositorio.igp.gob.pe/bitstreams/84b5d2d2-41a8-44d6-81b3-712cb75b3e9b/download974d6d16348e2c030650c50ae4ab7212MD53TEXTThree-Dimensional coherent radar imaging- Lessons from the Jicamarca MST experiments.PDF.txtThree-Dimensional coherent radar imaging- Lessons from the Jicamarca MST experiments.PDF.txtExtracted texttext/plain1https://repositorio.igp.gob.pe/bitstreams/5a0ddf0d-f1ab-43df-82ec-5f8d46bb8a17/download68b329da9893e34099c7d8ad5cb9c940MD5420.500.12816/678oai:repositorio.igp.gob.pe:20.500.12816/6782024-10-12 22:18:44.244open.accesshttps://repositorio.igp.gob.peRepositorio Geofísico Nacionalbiblio@igp.gob.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
