Book excerpt: The report describes an adaptive state estimator that can significantly improve the passive range and depth determination of a randomly maneuvering target. The target in this study is a submarine, which, while being tracked, performs large-magnitude depth changes at times unknown to the tracking submarine. Present passive tracking techniques usually utilize a Kalman filter to process the azimuth and/or elevation observations. A Kalman filter will theoretically give the 'best' estimates of target range, depth, and velocity when the system and measurement errors can be modeled as Gaussian processes. The main difficulty in using a Kalman filter in passive tracking applications is that large bias errors invariably develop as the target makes large alterations in velocity or depth. A technique for including a feedback-type learning processor in conjunction with the Kalman filter has been found to greatly reduce bias errors produced by the maneuvering target. (Author).

This book was released on 1981 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report examines the problem of adaptively tracking a maneuvering target in two dimensional space using passive time delay measurements. The target is free to maneuver in velocity and to make depth changes at times unknown to the observer. Tracking is accomplished by using the basic polar model of target and observer motion previously developed, and included in this report for the convenience of the reader. However, the important distinction is that now a nonlinear prefilter has been added to the tracking system. This leads to two major benefits: the first, is that the need for extended Kalman filters is completely eliminated which gives the tracking system a much a larger degree of robustness than it previously had. The second benefit is a decoupling of the depth estimator from the polar range estimator, which considerably reduces the computational level of the adaptive tracking system. (Author).

This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Research Workshop on Issues in Acoustic Signal/Image Processing and Recognition was held August 5-9, 1982 at the Cappuccini complex in San Miniato Italy. The Workshop was primarily concerned with the underwater acoustic signal processing and seismic signal analysis and a major effort was made to link these topics with pattern recognition, i~ge processing and artificial intelligence. Major issues and new approaches in these interrelated areas were closely examined in the Workshop. In addition to paper presentations three discussion sessions were held on! (1) spectral analysis in underwater acoustics, (2) seismic wave propaga tion, seismic imaging and migration, and seismic inversion, and (3) unresolved issues and future directions. This Proceedings volume includes most presentations made at the Workshop. The publication, like the meeting itself, is unique in the sense that it provides exten sive interactions among the closely related areas stated above. Such interactions which usually result in the integration of different systems or approaches are certainly much needed to achieve some performance breakthrough while individual systems or approaches reach their performance limit. I am grateful to all participants for their active participation that makes the Workshop very productive, and to Dr. Lewis J. Lloyd and Dr. Ralph Goodman for their help to arrange an informative visit to the SACLANT ASW Research Centre for the Workshop participants. I am confident that this publication will be equally produc tive to report important current research results and near-future research activity particularly in underwater acoustic signal processing.
