Se realiza el análisis de relación entre la reducción de datos y la confiabilidad en la reconstrucción de señal provista por MPM para señales provenientes de barcos reales, teniendo en cuenta parámetros de tiempo de procesamiento y correlación de señal. La reducción de datos se realiza con el fin de usar de manera óptima el ancho de banda de un canal inalámbrico que facilite la comunicación entre varios sensores y un nodo central, en el que posteriormente, se realiza el proceso de localización. Una vez determinadas las características específicas de las señales y luego de la aplicación de MPM, se busca usar la información proveniente de cada sensor para calcular la localización de los objetivos usando TR. De igual manera se evalúa la efectividad del método considerando variaciones en las características de la reconstrucción provista por MPM y teniendo en cuenta factores de ruido aleatorio presente en el proceso de propagación de señal a través del medio. (Texto tomado de la fuente)This master thesis document will present the implementation of a strategy of information reduction and the location of objectives in a simulated environment. This strategy is based on the processing of submarine acoustic signals, using Matrix Pencil (MPM) and time-reversal (TR) methods. It analyzed the relationship between data reduction and the reliability of the reconstructed signal provided by MPM. This information was coming from real boats and the analysis was done taking into account parameters of processing time and signal correlation. Data reduction was done to optimally use the bandwidth of a wireless channel which allows to connect of a lot of sensors with a central node and made the localization process. Once the specific characteristics of the signals were established and then using MPM, it is used TR to estimate the location of the objectives. It was evaluated the effectiveness of the proposed method considering the variations in the characteristics of the reconstructed signals given by MPM and using also random noise factors due to signal propagation through the medium.MincienciasUniversidad Nacional de ColombiaEscuela militar de cadetes "Almirante Padilla"MaestríaMagíster en Ingeniería - Ingeniería ElectrónicaProcesamiento de señales digitalesxiv, 56 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Ingeniería ElectrónicaDepartamento de Ingeniería Eléctrica y ElectrónicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá530 - Física::537 - Electricidad y electrónicaECUACIONES ONDULATORIASWave equationsSingularidadesSVDReconstrucciónLocalizaciónAncho de bandaMétodo de Matrix PencilMétodo de Time ReversalInversión en el tiempoCorrelaciónSingularitiesLocalizationBandwidthMatrix Pencil methodTime Reversal methodReversal on the timeCorrelationReconstructionEvaluación de estrategia de localización de barcos, usando señales acústicas comprimidasEvaluation of ship location strategy, using compressed acoustic signalsTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMRedColLaReferenciaM. d.
