Method For Tracking Targets With Hyper-Spectral Data

US Patent:
7212652, May 1, 2007
Filed:
Jul 7, 2003
Appl. No.:
10/614433
Inventors:
Marcus L. Graham - North Kingstown RI, US
Roy L. Streit - Portsmouth RI, US
Michael J. Walsh - Somerset MA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G06K 9/00
US Classification:
382103, 382107, 235411, 348169
Abstract:
In the present invention, the histogram model used in H-PMHT is extended to treat the problem of tracking using hyper-spectral data. Completely general spectral density functions are handled via the use of non-parametric methods. The present invention is not restricted to derivations based on knowledge of the spectral character of the source being tracked. The source spectrum can be estimated in a non-parametric fashion based on an initial track, and this allows the invention to adapt to the source spectrum in situ. The resulting method has improved crossing track performance on sources that have some degree of spectral distinction and will perform no worse than regular H-PMHT on sources that have identical spectral densities.

Apparatus And Method For Long Term Tracking For Asw Applications

US Patent:
7627424, Dec 1, 2009
Filed:
Jun 6, 2005
Appl. No.:
11/147650
Inventors:
Robert C. Gibbs - Jamestown RI, US
Michael J. Walsh - Somerset MA, US
Maria C. Santos - Bristol RI, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01C 21/00
US Classification:
701205, 701207
Abstract:
An apparatus and method are disclosed that provide target motion analysis with the ability for having long-term tracking. The apparatus and method provide a leg builder program that monitors successive positional updates from a target and converts the updates into a leg format. The leg format consists primarily of start time, latitude/longitude, time on leg, and end latitude/longitude. The leg format is continuously updated so long as the course of the target is steady. The leg format further embodies routines that provide for a spherical earth model and also for handling unstable course and speed conditions from a target.
