A system applicable to acoustic, seismic, electromagnetic, hydrodynamic, and shock waves utilizing a map between signal time series and signal vectors defining the mathematical wave field model characterizing the signal's wave field. This map is developed from wave models relating field values to those on surfaces and corresponding uniqueness theorems. The system should allow for improved resolving power in bearing and elevation for discrimination of sources; detection and direction finding for signals below the average background level; detection based upon resolving power and signal vector characteristics rather than signal to noise ratio; reconstruction of signals of resolved sources for their transmitted information content; and multiple modes of operation. Adaptive incorporation of known undesired signals into the noise background and/or treatment of asymmetric background noise fields is permitted through use of a noise metric-based map yielding signal direction in the presence of diffraction effects.

These sensors may be acoustic and/or electromagnetic sensors. The covariance matrix is replaced with Toeplitz matrix.

179	Bias estimating method for a target tracking system	US09530666	2000-05-03	US06359586B1	2002-03-19	Egils Sviestins
The present invention is in general related to automatic alignment in multi-sensor target tracking. The process of the invention repeatedly generates estimates for sensor bias errors (b) by minimising a function, given on one hand by the magnitude of the discrepancy between measurements (M) and a measuring model, where the measuring model is a function of the unknown target location and unknown bias parameters, and on the other by the bias parameters and their predetermined statistical distributions (15). In a preferred embodiment of the present invention, the minimizing step is performed by linearising components of the function around an approximate target position (normally obtained from the tracker (10)) and around nominal (typically zero) bias errors, and the function is subsequently minimized with respect to target positions as well as to the bias parameters (b). In addition, possible time dependence of the bias parameters are modelled by the incorporation of process noise.
180	Method and system for real-time information analysis of textual material	US717757	1996-09-23	US5761685A	1998-06-02	William H. Hutson
A multi-dimensional processing and display system that is used with textual data to provide a system by which large volumes of such textual data may be efficiently sorted and searched. Textual data that is input to the multi-dimensional processing and display system is from one or more documents that are reformatted and translated into one or more numeric matrices. The matrices are modified to enhance and/or suppress certain words, phrases, subjects, etc. Thereafter, a single two-dimensional data is formed by concatenating the numeric matrices. The multi-dimensional processing and display system creates and maintains a historical database which is also concatenated in the two-dimensional matrix. Once the textual data is in the form of a two-dimensional matrix, the data can be analyzed efficiently, for example, using singular value decomposition (SVD). In doing so, the two-dimensional concatenated matrix is decomposed to obtain a compressed form of the numeric matrix. Certain data elements in the two-dimensional matrix may be enhanced, while certain other data elements may be suppressed. After data enhancement and/or suppression, the two-dimensional matrix is partitioned and rearranged to form an enhanced multi-dimensional matrix. All or portions of the enhanced multi-dimensional matrix are then visually displayed. Lexical, semantic, and/ or textual constructs of interest may be displayed as opaque objects within a three-dimensional transparent cube, enabling a user to review many documents quickly and easily.
