1. A method of tracking a target, comprising the steps of:
- receiving, at a plurality of sensors at a plurality of locations, a plurality of signals from the target on a wide frequency band of one or more of aircraft, vehicle, vessel, and fixed target emitted signals;
time-stamping the plurality of signals with time stamps indicating when the signals arrive at the plurality of locations; and
determining position of the target using time difference of arrival of the plurality of signals at the plurality of locations,wherein one or more of the sensors is installed at one or more of a fixed location, buoy-mounted, ship mounted, aircraft mounted or unmanned aerial vehicle mounted.

Abstract
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.
