Various techniques have been developed for either binary or multiple hypotheses decision fusion. However, most of them do not address the challenges that come with the changing quality of sensor data. In this paper we investigate adaptive decision fusion rules for multiple hypotheses within the framework of Dempster-Shafer theory. We provide a novel learning algorithm for determining the quality of sensor data in the fusion process. In our approach each sensor actively learns the quality of information from different sensors and updates their reliabilities using the weighted majority technique. Several examples are provided to show the effectiveness of our approach","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130475887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work is motivated by the difficulty of associating ESM sensor data with large measurement errors to closely-spaced radar tracks. The algorithm presents a novel approach to fusing identity information. It assigns to multiple radar tracks the identity information content of an ESM track. The identity fusion is performed using the Dempster-Shafer rule of combination. A weight based on the positional likelihood of association is included in the fusion process. Simulations of a group of targets for which angular distances are similar to the measurement errors of the ESM sensor are presented. Results show that it is possible to correctly identify a target within the group in a reasonable time interval without having to wait for the group to completely separate","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127921910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is designed to provide element or beam-level data, in the time or frequency domain, in either a real or basebanded format. It is capable of handling any number and variety of sources, receivers, and targets with arbitrary, rigid-body trajectories in three dimensions. In general, simulated data will contain contributions from all sound sources: ambient noise, reverberation, source direct blasts, target echoes, target radiated noise and receiver self noise. The underlying signal generation, acoustic propagation, and physical interactions are performed using the sonar simulation toolset (SST), which in turn uses the comprehensive acoustic sonar system (CASS) and Gaussian ray bundle (GRAB) algorithm for eigenray generation. Acoustic propagation is ray-based only but is range dependent. The system may be used for generating active, passive or combined active/passive scenarios. It may also be used to inject active or passive targets into existing, real-world data sets","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"R-30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126629517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has connections to random graph theory from mathematics as well as to social network analysis and recent work by physicists interested in understanding the behaviour of large, interacting networks. Network models are important for information fusion in two manners. First, the command and control networks of distributed information fusion systems must be designed in such a way that they are both robust against failures and attacks and so that information spreads quickly in them. Second, network models and social network analysis is an important tool to use when analyzing the opponents facing us in international operations. In this paper, we describe the basics of complex network models and point out how they can be used for both these purposes.

In this paper a new class of approximation algorithms to solve the MAP is presented, named K-SGTS, and its effectiveness in multi-target multi-sensor tracking situations is shown.

In this paper, we outline our use of these algorithms for situation awareness in the maritime domain. Our algorithms take real-time tracking information and learn motion pattern models on-the-fly, enabling the models to adapt well to evolving situations while maintaining high levels of performance. The constantly refined models, resulting from concurrent incremental learning, are used to evaluate the behavior patterns of vessels based on their present motion states. At the event level, learning provides the capability to detect (and alert) upon anomalous behavior. At a higher (inter-event) level, learning enables predictions, over pre-defined time horizons, to be made about future vessel location. Predictions can also be used to alert on anomalous behavior. Learning is context-specific and occurs at multiple levels: for example, for individual vessels as well as classes of vessels.
