Abstract(s)
No âmbito do item #2 (Protection of Harbours and Ports) – Defence against
Terrorism Programme of Work (DAT PoW), a Marinha Portuguesa propôs o
desenvolvimento de um sistema de apoio à decisão, denominado SAFEPORT, que
pretende apoiar o planeamento das operações de segurança relacionadas com a defesa
portuária aquando da presença de uma força NATO numa zona portuária
potencialmente hostil. No âmbito da defesa portuária interessa conhecer qual a
capacidade de deteção do par sensor/alvo na área a ser monitorizada, aplicando, para o
efeito, conceitos da teoria de busca em ambiente marítimo e modelação de performance
de sensores. Sendo assim, a elaboração de um caderno de provas para avaliação de
sensores Eletro-óticos é um requisito fundamental. Este visa a recolha de dados a partir
de experiências de campo que possibilitem a estimação da capacidade de deteção de um
sensor relativamente a um alvo em condições operacionais e ambientais específicas.
A elaboração deste caderno é baseada nos conceitos de Avaliação Operacional (AO),
atividade desenvolvida em âmbito militar por alguns países, como Estados Unidos da
América, Austrália e Brasil e tem por objetivo entregar para soldados, marinheiros e
fuzileiros sistemas aptos a cumprir uma missão de combate.
O caderno é composto por um plano de teste e um plano de avaliação para a
realização de experiências de campo com vista à recolha de dados para a estimar os
modelos de deteção de sensores eletro-óticos. São identificados os Aspetos Críticos, os
Elementos Essenciais de Análise (EEA), as instruções para a condução de experiência
de campo com controlo das variáveis para as quais se pretende recolher informação e a
Metodologia de Análise.
É também averiguada uma alternativa para o local da realização da experiência de
campo, face à opção atualmente em estudo pelo GT-DATPOW. Finalmente são tecidas
algumas considerações sobre a aplicação da AO na Marinha Portuguesa.
Within the item #2 (Protection of Harbours and Ports) – Defence against Terrorism Programme of Work (DAT PoW) the Portuguese Navy leadership proposed the development of an Decision Support System, named SAFEPORT, to support operations planning in an harbour defence scenario with a NATO expeditionary fleet and a terrorist threat is assumed. When considering harbour defence, it is of particular interest to determine sensor/target combined detection capability within a monitored area, using concepts, such as search theory and sensor performance modelling to achieve it. As a result, the elaboration of an electro-optic evaluation test book is a root requirement. This test book aims to estimate a sensor’s detection capability regarding a target within specific operational and environmental conditions, through the conduction of field trials. The elaboration of a test book is based upon the concepts of Operational Test and Evaluation, a military related activity developed in some countries, such as the United States, Australia and Brazil, which has the objective of providing soldiers, sailors and marines combat mission ready and fit systems. A test book is composed by a test and an evaluation plans, in order perform field trials with the intent of gathering data to estimate the electro-optic sensor’s models of detection. Critical Aspects, Analysis Essential Elements, the field trial’s intended variable collection control instructions and Analysis Methodology are identified. An alternative location for the field trials realization, in light of the GT-DATPOW’s current option, is also ascertained. Finally, some light is shed regarding the application of the Operational Test and Evaluation within the Portuguese Navy.
