Ability to stimulate the unintentional electromagnetic emissions to allow detection from a farther distance than without stimulation and better ability to locate the device.
About
Non-Confidential Abstract of Invention: All active electronic devices radiate electromagnetic energy. Since the levels of these electromagnetic emissions are well above instrument noise levels, it is possible to detect and identify a device based on its electromagnetic emissions. It has been demonstrated that these electromagnetic emissions are unique to each electronic device. The present invention exploits the use of these unintentional electromagnetic emissions for detection and identification of an electronic device from a distance. The invention also can stimulate the unintentional electromagnetic emissions to allow detection from a farther distance than without stimulation and to allow better ability to locate the electronic device.
