Abstract
A millimeter-wave (MMW) based screening system is provided that may operate with an active sensor, a passive sensor, or in a dual mode using both the active and passive sensors. One or more such sensors are mounted so as to rotate along an axis that passes through a target region of detection, in which a person or object is positioned for screening. A reflector is disposed radially outward from the one or more rotating sensors to reflect MMW radiation between the sensors and the target region. The system may be employed as a portal screening system, and may include a structure having a wall and a roof, for rapidly screening persons for concealed objects. Algorithms may be employed to provide data output that avoids privacy issues.
Claims10
A millimeter-wave (MMW) screening system comprising:
- a first rotatable MMW sensor mounted in a structure and on an axis so as to rotate about the axis, the axis extending along an object viewing region scannable by the sensor;
- a reflector positioned away from the object viewing region and disposed so as to reflect MMW radiation received from the object viewing region to the sensor;
- and
- a display and processing terminal adapted to receive digital data derived from MMW signals from the first rotatable MMW sensor based on data collection from multiple positions of sensor rotation about the object viewing region, and to process said digital data to provide an image of the object viewing region.
