Enhanced surveilled subject imaging
First Claim
1. An imaging system comprising:
- an antenna assembly including at least a first antenna apparatus, each antenna apparatus configured to transmit toward and receive from a subject, including a person and any discernable objects with the person, in a subject position, electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz, from positions spaced from the subject position, the antenna assembly producing an image signal representative of the received radiation; and
a controller adapted to produce from at least a first portion of the image signal first image data corresponding to a first image of at least a portion of the subject having a first resolution, and to produce from at least a second portion of the image signal second image data corresponding to a second image of at least a portion of the subject having a second resolution greater than the first resolution.

Abstract
An imaging system can include an antenna apparatus configured to transmit toward and receive from a subject in a subject position, millimeter-wave electromagnetic radiation. A subject may include a person and any object or objects with the person. A controller can include a transceiver configured to operate the antenna apparatus and produce an output representative of the received radiation, and a processor adapted to produce from the transceiver output, image data representative of an image of the subject. At least a first portion of an image signal representative of radiation received by an antenna apparatus may be used to produce first image data representative of a first image of at least a portion of the subject. Second image data representative of a second image having resolution that is different than that of the first image may be produced from at least a second portion of the image signal.

21. An imaging system comprising:
-
an antenna assembly including at least a first antenna apparatus, each antenna apparatus configured to transmit toward and receive from a subject, including a person and any discernable objects with the person, in a subject position, electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz, from positions spaced from the subject position, the antenna assembly producing an image signal representative of the received radiation, the antenna assembly being adapted to operate selectively in a first mode to produce a first portion of the image signal, and in a second mode to produce a second portion of the image signal corresponding to a portion of the first portion of the image signal; and
a controller adapted to control operation of the antenna assembly, to produce from at least the first portion of the image signal first image data representative of a first image of at least a portion of the subject, and to produce from at least the second portion of the image signal, second image data representative of a second image corresponding to a portion of the first image, and to cause the antenna assembly to operate in the second mode in response to an indication associated with the second portion of the image signal determined from the first portion of the image signal. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method of surveilling a subject, the subject including a person and any discernabie objects with the person, the method comprising:
-
transmitting toward the subject in a subject position, electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz, from positions spaced from the subject position;
receiving from the subject electromagnetic radiation emitted from the subject in response to the transmitted electromagnetic radiation;
producing an image signal representative of the received radiation; and
producing from the image signal, first image data corresponding to a first image of at least a portion of the subject having a first resolution, and second image data corresponding to a second image of at least a portion of the subject having a second resolution greater than the first resolution. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

53. An imaging system comprising:
-
means for transmitting toward the subject in a subject position, electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz, from positions spaced from the subject position;
means for receiving from the subject electromagnetic radiation emitted from the subject in response to the transmitted electromagnetic radiation;
means for producing an image signal representative of the received radiation; and
means for producing from at least a first portion of the image signal, first image data corresponding to a first image of at least a portion of the subject having a first resolution; and
means for producing from at least a second portion of the image signal, second image data corresponding to a second image of at least a portion of the subject having a second resolution greater than the first resolution. - View Dependent Claims (54, 55)

56. One or more storage media having embodied therein a program of commands adapted to be executed by a computer processor to:
-
receive an image signal generated in response to an interrogation of a subject, including a person and any objects carried by the person, with electromagnetic radiation in a range of about 100 MHz to about 2 THz;
produce from at least a first portion of the image signal, image data corresponding to a first image of at least a portion of the subject; and
produce from at least a second portion of the image signal, image data corresponding to a second image of at least a portion the first image. - View Dependent Claims (57, 58)
