 | Methods to individually allocate credit to multiple sensors assist Army decision makers during Objective Force development and integration. Sensor credit apportionment supports a knowledge-based common operating picture by providing a means to assess and compare the variety of automated and human sources that contribute to the common operating picture (U.S. Army White Paper, 2001). This thesis develops and assesses such a method. The method determines the contribution of individual sensors ... |

|
 | Low frequency active sonar has been highlighted by a number of NATO nations as an important component of the next generation of undersea defense systems. However, the use of low frequencies in a shallow water environment is known to result in a high false alarm rate due to the large number of reverberation returns that can overload automatic tracking and classification algorithms. The SACLANT Undersea Research Centre is currently investigating ... |

| In modern spy movies such as Enemy of the State and Patriot Games, scientists magnify digital satellite imagery to determine the identities of people captured on surveillance video. These individuals appear rather blocky at the coarsest resolution scales because of undersampling by the image sensor array, but they become remarkably clear after zooming in on a particular region- of- interest.

| A continuing challenge for multisensor data fusion systems is the problem of estimating the accuracy or performance of the system. This is especially difficult for dynamic adaptable systems such as modern integrated air defense systems (IADS). These systems utilize multiple sensors (e.g., radar, identification-friend-foe (IFF) systems) to observe airborne targets to develop accurate tracks and to identify the observed targets. Modern IADS have the capability to dynamically reconfigure themselves to ... |

| A new approach is taken to address the various aspects of the multi- sensor, multi-target tracking (MTT) problem in dense and noisy environments. Instead of fixing the trackers on the potential targets as the conventional tracking algorithms do, this new approach is fundamentally different in that an array of parallel-distributed trackers is laid in the search space. The difficult data-track association problem that has challenged the conventional trackers becomes a ... |

| Bayesian techniques have been employed to combine, or fuse, reports from multiple target identification (ID) sensors. Recent work has shown that a 'cost' criterion can be used to make optimum target declaration decisions from the Bayesian representations of the ID sensors. However, the 'cost' method, as previously formulated, only works when choosing between two types of target declarations (e.g., friend vs. hostile). This paper provides an alternative formulation to the ... |

| Multiple sensor arrays distributed over a region provide the means for accurate localization of the (x, y) position of a source. When microphone arrays are used to measure aeroacoustic signals from ground vehicles, random fluctuations in the air lead to frequency-selective coherence of the signals that arrive at widely-separated arrays. We have shown previously that even in cases of imperfect spatial coherence, improvements in source localization accuracy are possible when ... |

| A sensor is a device used to sense or measure physical phenomena. Thus, sensors may detect electrical, mechanical, optical, chemical, tactile, or acoustic signatures of an object or scene. Objects that may be difficult to discriminate using a single sensor are often differentiated with a multiple sensor system that exploits several signature phenomena. The application of multiple sensors (and the fusion of their data) offers numerous potential performance benefits over ... |
