Systems and methods for multi-unit collaboration for noninvasive detection of concealed impermissible objects

1. A method comprising:

performing, by a first coherent radar system on a chip configured to operate in a terahertz range between 0.1 THz and 1 THZ, a first radar scan of a target, the first coherent radar system being in physical contact with a first non-physical scanning device;

receiving, at the first non-physical scanning device, first scanning data from the first radar scan;

sending a coordination signal to a second non-physical scanning device;

performing, by a second coherent radar system on a chip configured to operate in the terahertz range between 0.1 THz and 1 THz, a second radar scan of the target, the second coherent radar system being in physical contact with the second non-physical scanning device;

receiving, at the second non-physical scanning device, second scanning data from the second radar scan;

sending the first and second scanning data to a processor for a determination as to whether an impermissible object has been detected.

2. The method of claim 1 , wherein the processor is in physical contact with at least one of the first and second non-physical scanning devices.

3. The method of claim 1 , where the processor is in physical contact with neither the first nor the second non-physical scanning devices.

4. The method of claim 1 , further comprising:

rendering an image based on the first and second scanning data.

5. The method of claim 1 , further comprising:

receiving, at the first non-physical scanning device, instructions to move the first non-physical scanning device to a first desired location.

6. The method of claim 5 , wherein the coordination signal includes at least one of:

instructions to move the second non-physical scanning device to a position relative to the first non-physical scanning device, or

visual images of the target, or

instructions to scan the target.

7. The method of claim 6 , further comprising:

sending, to the processor, an image of a region for scanning;

selecting the target based on at least one of the visual images.

8. A method comprising:

receiving, at a first non-physical scanning device, a signal to move to a first position that satisfies a position policy;

selecting a target;

scanning, by a first coherent radar system on a chip in physical contact with the first non-physical scanning device and configured to operate in a terahertz range between 0.1 THz and 1 THZ, a first radar scan of a target;

receiving, at the second non-physical scanning device, instructions to move to a second position, the second position being related to the first position;

scanning by a second coherent radar system on a chip in physical contact with the second non-physical scanning device and configured to operate in the terahertz range between 0.1 THz and 1 THz, a second radar scan of a target;

sending to a processor a first data set from the first coherent radar system on a chip;

sending to the processor a second data set from the second coherent radar system on a chip;

determining, at the processor, based on the first data set and second data set, whether an impermissible object has been scanned.

9. The method of claim 8 , wherein the selecting a target is performed on a processor in physical contact with at least one of the first non-physical scanning device and the second non-physical scanning device.

10. The method of claim 9 , further comprising:

if an impermissible object has been scanned, rendering, based on the first data set and the second data set, a visual representation of the target and the impermissible object, coherent radar system on a chip.

11. The method of claim 9 , wherein the rendered visual representation includes a first visual representation based on the first data set and a second visual representation based on the second data set, the first visual representation being rendered adjacent to the second visual representation.

12. The method of claim 11 , wherein the determining is performed at a handheld control device proximate to the target.

13. The method of claim 9 , where the determining is performed at a central command center.

14. The method of claim 8 , wherein the selecting a target is performed on a processor in physical contact with a non-physical scanning device.

15. The method of claim 8 , wherein the sending the first data set and second data set occurs over a wireless network.
