Abstract(s)
À semelhança de Marinhas de diversos países, a Marinha Portuguesa (MP) aderiu à
utilização da simulação para estudar a adequabilidade, a eficácia e a eficiência dos sistemas
de armas e sensores dos navios, tendo, em 2006, adquirido o software de simulação SADM
- Ship Air Defence Model.
Esta dissertação tem como objetivo a utilização do referido software de simulação,
na modelação dos engodos antimíssil em uso na MP. Segue-se então a validação dos
modelos, que passará pelo confronto dos resultados reais vs. resultados simulados, o que
permitirá aferir a fiabilidade do modelo ou a possível deteção de alguma lacuna existente.
Depois de validados, os modelos serão utilizados na simulação, análise e desenvolvimento
de técnicas de defesa antimíssil, com recurso a medidas de softkill.
Assim sendo, este trabalho inicia com uma breve explicação relativa ao
funcionamento de alguns tipos de mísseis antinavio contemporâneos, bem como uma
abordagem descritiva dos sistemas de defesa antimíssil softkill, isto é, sem recurso à
destruição física do míssil, existentes nos navios das classes “Vasco da Gama” e
“Bartolomeu Dias”. Segue-se a descrição das vantagens e desvantagens da simulação,
segundo vários autores, e a apresentação do modo de funcionamento do SADM. Definido o
modo de funcionamento do software, é então abordada a parametrização dos modelos, isto
é, são referenciados quais os dados (parâmetros) introduzidos, de modo a obter um modelo
dos engodos. Seguidamente são apresentados alguns cenários, onde é testada, com o
auxílio da simulação, a utilização de engodos antimíssil, nomeadamente a confirmação da
sua efetividade. Por fim, apresentam-se as conclusões, que respondem à questão do
trabalho, abordando também a comparação entre os resultados obtidos através das
simulações em SADM e os resultados reais dos EW Trials, constantes dos respetivos
relatórios.
Similarly to navies from other countries, the Portuguese Navy has been using modelling and simulation (M&S) to study the effectiveness and efficiency of weapon systems and ships’ sensors, since 2006, when the simulation software SADM - Ship Air Defence Model - was acquired. This paper aims to use SADM in the modelling of missile decoys used by the Portuguese Navy. The models’ validation will pass through the confrontation of real results with simulated results, which will assess the reliability of the model or the detection of any possible gap. Once validated, the models will be used in the simulation, analysis and development of techniques for missile defence, using softkill measures (systems that don’t involve the physical destruction of the missile). Therefore, this paper begins with a brief explanation about the operation of some missile types, as well as a descriptive approach of softkill systems existing on "Vasco da Gama" and "Bartolomeu Dias" class frigates. Afterwards, there is a discussion on simulation’s advantages and disadvantages, according to several authors, and the presentation of the SADM operation. Next, is presented the data input featuring the kind of scenario that is intended to build. There are also some scenarios starring the use of antimissile decoys, with the aid of the simulation, which include a confirmation of its effectiveness. Finally, some conclusions were drawn, based on the comparison between the results obtained through simulations SADM and actual results of EW Trials.
