Abstract(s)
Este trabalho analisou a exequibilidade de empregar sistemas não tripulados (SNT)
como apoio às operações de busca e salvamento (SAR) marítimo costeiro. Primeiramente,
foram caracterizados os SNT em operação na Marinha, na Força Aérea, e os desenvolvidos
pelo projeto ICARUS. Seguidamente, foi realizada uma descrição estatística, geral e sazonal,
dos eventos de SAR marítimo, ocorridos entre 2013 e 2021, na Search and Rescue Region
Lisboa. Por último, foi identificado um projeto inovador, da Marinha, passível de apoiar as
operações SAR costeiro.
Da análise à exequibilidade de empregar os meios estudados, relativamente aos
eventos de SAR analisados, os dados sugerem que os modelos de asa fixa em uso nas Forças
Armadas poderiam ter sido empregues em 94% dos casos, enquanto que o de asa rotativa
em 34%. Sendo que os SNT de superfície da Marinha se encontram em fase de prova de
conceito, foi analisado o U-Ranger do projeto ICARUS, cuja reduzida taxa de aplicabilidade
de 33%, sugere a necessidade de analisar outras plataformas, mais robustas e resilientes. Por
último, constatou-se que o projeto de edificação da rede de radares costeiros de alta frequência, e produtos resultantes, poderá ser um forte aliado às operações SAR marítimo
costeiro.
Abstract: This work analysed the feasibility of employing unmanned systems (US) to support coastal maritime search and rescue (SAR) operations. Firstly, the US currently operating in the Navy and Air Force, and those developed by the ICARUS project were characterized. Afterwards, a statistical description of the maritime SAR events, that occurred between 2013 and 2021 in the Search and Rescue Region Lisbon, was carried out. Finally, an innovative project being developed by the Navy that could greatly enhance the outcome of coastal SAR operations was identified. The data analysis suggests that the fixed-wing models currently in use by the Armed Forces could have been employed in 94% of the studied cases, and the rotary-wing model in 34%. Given that the Navy's surface US are in the proof-of-concept phase, the U-Ranger from the ICARUS project was analysed, whose low applicability rate of 33% implies that a new analysis should be performed, taking in consideration other, more resilient, platforms. Finally, it was found that the project for the edification of the coastal high-frequency radar network, and its resulting products, may be a strong asset for all coastal maritime SAR operations.
