COMBIS version 3.0

The development of COMBIS has focused on passive sensor networks. In order to evaluate different scenarios such as protection of our home basin, during transit or during covert operations there has been a need to develop a sensor network tool within COMBIS. Today, COMBIS has the capability of demonstrating new models/functions/concepts in virtual operation areas. This hopefully leads to an increased dialogue with users both on a tactical and operational level. Our vision of the future is that COMBIS is used as a test platform for new ideas which then are implemented in simulation frameworks. Then, scenarios can also be simulated and more intensive feedback to researchers can take place. The implementations in COMBIS version 3.0 embrace; a map editor, a sediment editor, a tool for setting up passive sensor networks, defining the oceanographic environment and sediment parameters, simple acoustic sensor models and setting detection parameters. The passive sensors include both acoustic and electromagnetic surveillance methods. Detection probabilities are calculated using the sonar equation and the corresponding electromagnetic simplification (ELFE equation).
