Abstract
An apparatus, method, and computer program product that intentionally illuminate at least one target device with electromagnetic energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.). The target device, which may be an unpowered data storage device, acts as a non-linear mixer and is forced to emit radiative signals containing information about the target device behavior, state, and physical characteristics. Embodiments receive the forced emissions, extract useful data, and analyze the data to determine target device characteristics (e.g., a target device type, based on a comparison of data from known types). Embodiments control the illumination so the forced emissions radiate from an enclosure without interfering with tactical communications, and so that stored target device data is not affected. Embodiments can locate a hidden target device via the strength and directionality of the forced emissions. The apparatus is portable for use by military, intelligence, and security personnel.
