Abstract
Outlines issues pertaining to the development of a coherent environment for target tracking in the presence of unknown manoeuvers, using multiple dissimilar sensory groups. The problem has been decomposed into three parts: Firstly, the generic fusion of estimates derived from each independent sensory group to yield an optimal global estimate; secondly, the processing of purely local information at each sensory group to provide accurate predictive estimates; finally the treatment of non-sufficient sensory groups. To address the first problem, a decentralized hierarchial filtering structure amenable to parallel multi-processor implementaion, requiring minimal communication is described. The second issue can be equivacated to the problem of a single sensory group, monitoring a single manoeuvring target. A highly computationally efficient solution is achieved by the utilization of a multiple structure adaptive target tracking scheme. This procedure provides coherent off-line segmentation of a hemisphere in 3-D space to yield decision regions, which are utilized to select an appropriate filter structure. A tractable solution to the third problem can be realized by the use of passive estimation techniques.
