摘要： A system for detection of optical type devices being used by an enemy sniper subject without alerting the enemy is shown. A coherent laser beam of a wave length in the visible color range, is sent along an axis and passing through a beam splitter device. A detection means is arranged to generate a signal when it detects retro-reflections from the target optical devices or subject including clutter reflections in a 180 degree direction relative to axis. The detection means is coaxially mounted with the source of illumination with a second detection means off axis therefrom to generate a second detection signal when it detects clutter reflections from the target optical devices or subject. A comparator means forms a difference signal between the retro-reflected detection signal and the second detection signal and indicates when the difference signal exceeds a predetermined threshold.

摘要： A method of operating a sensor system may include the steps of sensing a predetermined area including a first object to obtain first sensor data at a first predetermined time, sensing the substantially same predetermined area including the first object to obtain second sensor data at a second predetermined time, determining a difference between the first sensor data and the second sensor data, identifying a target based upon the difference between the first sensor data and the second sensor data, identifying a material of the target and determining a target of interest to track based upon the material of the target.

摘要： An apparatus and method for automatic recognition and identification of concealed objects and features thereof, such as contraband in baggage or defects in articles of manufacture, is disclosed. The apparatus uses multiple energy X-ray scanning to identify targets with a spectral response corresponding to a known response of targets of interest. Detection sensitivity for both automatic detection and manual inspection are improved through the multiple-energy, multispectral technique. Multichannel processing is used to achieve high throughput capability. Target identification may be verified through further analysis of such attributes as shape, texture, and context of the scan data. The apparatus uses a statistical analysis to predict the confidence level of a particular target identification. A radiograph, CT image, or both may be reconstructed and displayed on a computer monitor for visual analysis by an operator. Finally, the apparatus may receive and store input from the operator for use in subsequent target identification.
