Acesso em:.https://repositorio.ufpa.br/handle/2011/11001This work aims the application of optimization techniques to detect and record lightning electromagnetic waveforms. As a result of the optimization techniques developed on this Thesis, it is presented the “Lightning Detection and Waveform Storage System - (LDWSS)”. The main optimized points were: cost of the device; improvements of its detection dynamic range; development of a mobile device; possibility to detect in a multi-band way; and calibration in order to infer peak currents from remote measurements of lightning electric fields. The developed system was validated through comparison of a return stroke data in lightning triggered using the rocket-and-wire technique at the International Center for Lightning Research and Testing - ICLRT, of National Lightning Detection Network – NLDN data, and data from the Lightning Observatory in Gainesville - LOG. The main usage of the optimized system is on the investigation of lightning physics and effects, mainly in the Amazon region. As a result of using the system were obtained: a better understanding about Compact Intracloud Discharge - CID; the characteristics of ionosphere heights computed using intraclound and cloud-to-ground lightning electric field waveforms; the conception of a lightning electric field waveform database containing more than 8 thousand waveforms of different types of lightning; and the implementation of the first continuous lightning electric field measurement system in the amazon region, localized at CESIPAM, Belem, PA.Acesso AbertoDescargas atmosféricasOtimizaçãoFormas de ondaAmazôniaLDWSS - Sistema de detecção e armazenamento de formas de onda de raiosLightningOptimizationWaveformsAmazon regionLDWSS - Lightning deteccion and waveforms storage systemTeseCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::MEDIDAS ELETRICASALTA TENSÃOSISTEMAS DE ENERGIA ELÉTRICA
