Patent 7548194 was granted and assigned to Raytheon on June, 2009 by the United States Patent and Trademark Office.
A hostile intention assessment system and method wherein a tracking sensor subsystem (e.g., radar) tracks targets relative to a critical asset. Determinations are made to assess if a first target is approaching a second target, and to assess if the second target is approaching the critical asset. If the first target is approaching the second target to hide in the radar shadow thereof and the second target is approaching sufficiently close to the critical asset, an alert is generated.
