Automatic Data Segmentation Module For Target Motion Analysis Applications
Automatic Data Segmentation Module For Target Motion Analysis Applications
US Patent:
5469374, Nov 21, 1995
Filed:
Jun 23, 1993
Appl. No.:
8/083404
Inventors:
Marcus L. Graham - North Kingstown RI
John F. MacDonald - Westport MA
Kai F. Gong - Pawtucket RI
Kathleen D. Keay - Fairhaven MA

Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G06F 1700
US Classification:
364516
Abstract:
A system having a device for comparing incoming data with hypotheses prevsly formed from prior data for providing new hypotheses on target information. It has application when the data source is from either single or multiple targets. The incoming datum to the system forms new hypotheses assuming the incoming datum is invalid, forms new hypotheses assuming the new datum begins a new segment of information, and forms new hypotheses assuming the new datum is associated with segments in prior retained hypotheses. The one hypothesis of the thusly formed new hypotheses with the greatest likelihood of target information is then selected for further analyzation and the hypothesis selected and other hypotheses are retained for further processing with new incoming datum.

Abstract:
A trajectory estimation system for estimating a trajectory of a target in sponse to a series of data items which generated in response to motion of the target. The trajectory estimation system includes a data segmentation means and a trajectory selection means. The data segmentation means processes the series of data items in accordance with a regression/multiple-hypothesis methodology to generate a plurality of segments, each having associated data items which have similar features. The trajectory selection means for processing said segments in accordance with a multiple-model hypothesis methodology to generate a corresponding statistically-supportable candidate trajectory motion estimate of target motion thereby to provide indicia of an overall trajectory of the target.
