Um Sistema de Vigilância Marítima Aplicado à Poluição Marinha por Petróleo no Brasil
Keywords in Portuguese

poluição do mar
Abstract in Portuguese
O principal objetivo deste trabalho é fazer uma análise exploratória a partir da bibliograa disponível, sobre o problema da poluição marinha no Brasil, em particular, da causada por derramamento de óleo. Analisando as principais fontes de poluição, no mundo e no Brasil, seus respectivos impactos ambientais e as metodologias de prevenção, controle, e de resposta adotadas, foi proposto um sistema de vigilância marítimo, capaz de vigiar grandes áreas independentemente das condições de luminosidade e de tempo. São apresentadas duas propostas, ambas baseadas em técnicas de sensoriamento remoto por radar, mas que se diferem principalmente pelas técnicas de aquisição de imagens e de processamento dos dados. Uma já consagrada mundialmente, a RAR (Real Aperture Radar ), e, a outra, a SAR (Synthetic Aperture Radar), que além de operar sob as condições adversas acima mencionadas, é capaz também de obter ótima resolução espacial independentemente da distância do sensor e do alvo. Este estudo demonstra a ineficiência das metodologias adotadas aqui no Brasil, para detectar, avaliar e combater óleo no mar e alerta para as vantagens de se utilizar técnicas modernas de vigilância marítima.

A Maritime Surveillance System Applied to Marine Pollution by Oil in Brazil

marine pollution
Abstract in English
The main objectives of this work are to make a exploratory analysis from the available readings, about the maritime pollution problem in Brazil, particulary that from oil spills. Analyzing the main sources of oil pollution around the world and in Brazil; their environmental impacts, and prevention, control and response methods adopted, a radar maritime surveillance system was proposed to investigate large areas, under rain or sun, at day and night time, agaist oil spills. It is presented two kind of sensor: the first one is RAR (Real Aperture Radar) wich is well known world wide, and the other one is the SAR (Synthetic Aperture Radar), wich is well suited to have good spacial resolution at any distance from the target. This work shows the needs to solve those problems related to maritime pollution in Brazil and the advantages to have a modem system to patrol the sea.
