Neural network based data fusion system for source localization
First Claim
1. A method for providing an estimate of the state of a moving contact using a device for estimating the state of said contact, said method comprising the steps of:
- inputting into said device information about a location of an observer platform at particular time intervals and information from at least one sensor about a position of a moving contact relative to said observer platform at each of said time intervals;
transforming said inputted information into a series of geographical grids with one geographical grid being formed for each reading from said at least one sensor;
combining grids corresponding to similar time intervals into a series of consolidated grid representation; and
analyzing said series of consolidated grid representations to produce an estimate of the state of said contact at a final point in time where an observation was made.

Abstract
A method is described for providing an estimate of the state of a moving contact. The method comprises providing a device for estimating the state of the contact, inputting information about a location of an observer platform at particular time intervals and information from at least one sensor about a position of the moving contact relative to the observer platform at each time interval into the device, transforming the inputted information into a series of geographical grids with one grid being formed for each reading of the at least one sensor; combining grids corresponding to similar time intervals into a series of consolidated grid representations; and analyzing the series of consolidated grid representations to produce an estimate of the state of the contact at a final point in time where an observation was made. The device of the present invention includes a grid stimulation block for forming the geographical grids, a fusion block for forming the consolidated grid representations, a correlation block for providing a path likelihood vector, and an estimation block for providing the desired estimate.

8. A system for generating an estimate of the state of a contact at a particular point in time, said system including:
-
means for transforming information about a location of an observer platform at particular points in time and about a relative position between said observer platform and said contact at said points in time into a series of geographical grids; means for combining ones of said geographical grids corresponding to similar time intervals into a series of consolidated grid representations; and means for analyzing said series of consolidated grid representations to produce an estimate of the state of said contact at a final point in time where an observation was made. - View Dependent Claims (9, 10, 11, 12, 13)
