This invention builds on previous industry techniques to correlate data from a variety of sources for the purposes of tracking and identifying aircraft, vehicles, and marine vessels in real time over a variety of different areas including oceans and mountainous terrain. Passive broadband tracking of aircraft emitters, and electronic fingerprinting of emitters, correlated with audio, video, infrared, primary radar and other information is employed to provide a comprehensive assessment of an aircraft's position, track and identification for a variety of applications including homeland security and search and rescue.
