Claim:
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 the person, and to produce a sensor signal representative of the detection of the given characteristic; 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 sensor data from the sensor signal, to relate the image data to the sensor data, and to produce from the related image data and sensor data, relational information data about whether the person is potentially carrying an object having the given characteristic.
