We introduce a radar imaging architecture which makes imaging at these long wavelengths more accessible, while enabling all of the following:
•Higher resolution imaging
•All of the electronics constrained to a small 10” x 10” space
•Fewer detectors necessary
•Better detection of specular (mirror-like) surfaces
•Multi-spectral imaging
•Time-resolved imaging (capturing Microwaves in flight)
The aim of our work is not just to detect objects, but also to form images in 3D. There are many advantages to being able to see how many limbs a person has and how tall they are; not just in what general area they are located.

Technique and device for through-the-wall audio surveillance
Abstract
Systems and methods are disclosed for detecting audible sound and/or the vibration of objects. Embodiments of the present invention are able to detect sound and other vibrations through barriers. One embodiment of the invention includes an RF transmitter configured to generate an RF signal having a frequency of at least 100 MHz and an unmodulated amplitude, an RF receiver configured to receive a reflected RF signal comprising an RF carrier having the same frequency as the generated RF signal that is amplitude modulated by an information signal and a signal processor configured to extract audio frequency information from the amplitude of the reflected RF signal.
Goverment Interests
[0002] The U.S. Government has certain rights in this invention pursuant to NAS7-1407 provided by the National Aeronautics and Space Administration, Office of Space Science.

so thats what she meant when she said microwaves can turn into cameras
i get it now
At least 50 U.S. law enforcement agencies quietly deployed radars that let them effectively see inside homes, with little notice to the courts or the public.

KellyAnne Conway is privy to some of the Top Secret intelligence briefing material that President Trump receives. Average people laugh and mock...but they do so out of ignorance.
