Multi-sensor surveillance portal
First Claim
1. A surveillance system comprising:
- a first sensor apparatus adapted to transmit toward and receive from a subject in a subject position, first electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz, from positions spaced from the subject position, the subject including at least a portion of a person in a subject position and detectable objects carried by the person, the first sensor apparatus producing from the received radiation, a first image signal representative of a first image of at least a portion of the subject;
a second sensor apparatus different than the first sensor apparatus, and adapted to detect a given characteristic of an object potentially carried by a person in the subject position; and
a controller adapted to control operation of the first and second sensor apparatus, and to produce, from the image signal, image data representative of the image of the at least a portion of the subject, and relational information about whether the person is carrying an object having the given characteristic.

Abstract
A surveillance system can include a first sensor apparatus configured to interrogate a subject, including a person and objects carried by the person, with millimeter-wave electromagnetic radiation for imaging the subject. A supplemental source provides additional information about the subject that is relatable to objects potentially carried by the person. Relational information relates the produced image signal and the subject information. The supplemental source may be a second sensor apparatus adapted to detect a given characteristic of an object potentially carried by a person in the subject position. Relational information about whether the person is carrying an object having the given characteristic may then be produced.

10. A method of surveilling a subject in a subject position, the subject including a person and objects carried by the person, comprising:
-
transmitting toward a subject in a subject position, first electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz, from positions spaced from the subject position, the subject including at least a portion of a person in a subject position and detectable objects carried by the person;
receiving from the subject reflected transmitted radiation;
producing from the received radiation, a first image signal representative of a first image of at least a portion of the subject;
detecting a given characteristic of an object potentially carried by a person in the subject position, not based on the first image signal; and
producing, from the image signal and the detected characteristic, image data representative of the image of the at least a portion of the subject, and relational information about whether the person is carrying an object having the given characteristic. - View Dependent Claims (11, 12, 13, 14, 15, 16)
