Scenario modelling [naval engagement, radar]

A model to determine the detection performance of an integrated sensor suite was specified by the Defence Research Agency (DRA) Portsdown and produced by Logica Defence & Civil Government Ltd. The model interfaced with data arrays representing each sensor and provided performance measures for phased array radars and other active and passive sensors against specific target parameters, environmental conditions and electronic warfare activity. The model was written using object oriented software techniques in C++ to run on an IBM PC under Microsoft Windows. The results of model runs are displayed dynamically using a dynamic data exchange (DDE) link to an Excel spreadsheet. A map is displayed illustrating how the scenario evolves the time. The main benefits of using Windows are that the user can readily define what ships and aircraft are in the scenario and the equipment fitted. The platform´s position, movement and equipment events are also specified as part of a consistent user interface
