Abstract: Multisensor data fusion is very important in the defence-oriented field. Data fusion can be used to integrate the individual sensor data into common operational picture of the battlefield in real-time in the area of interest (AOI). Reliable forming common operational picture of battlefield requires detecting, locating, identifying, classifying and monitoring of dynamic entities such as radio-emitters, different platforms, weapons, and military units. In this paper we discuss the ongoing efforts on development of a simulator for analysis and design of a distributed fusion-based tracking system. We have developed a fully interactive, graphical user interface based scenario generation tool for creating battlefield scenarios, and a simulation tool for running algorithm on scenarios and displaying the simulation results in an easy to understand fashion. Primarily, the battlefield simulator is described, as a basic part for data fusion. Using this battlefield simulator it is possible to test different techniques and methods for decision-level fusion approach. Decision-level fusion assumes that the results of the initial object detection and classification by the individual sensors are inputs to a fusion algorithm. Final classification occurs in the fusion processor using an algorithm that combines the detection, classification, and position attributes of the objects located by each sensor.

Key words: battlefield simulator, data fusion, decision level, sensor.
