Imaging system using WiFi signals

An imaging system comprising:

• (a) a receiver array, a display device, and a processor with an associated memory configured to store instructions, wherein the receiver array is configured to receive a scene signal reflected from a scene, wherein the scene signal is reflected in response to a plurality of incoherent communication signals being reflected off the scene, and wherein the plurality of incoherent communication signals are spatially and temporally incoherent at a point when reaching the scene;
• and
• (b) the instructions cause the processor to construct a reconstructed scene by:
• receiving at least three incoherent communication signals reflected off the scene at the receiver array;
• determining a scene visibility based on the at least three incoherent communication signals;
• identifying a sampling function;
• calculating a sampled visibility based on the scene visibility and the sampling function;
• and
• performing an inverse Fourier transform of the sampled visibility to construct the reconstructed scene.

An passive incoherent millimeter-wave imaging method comprising:

• receiving, from a plurality of communication devices, a scene signals including a plurality of incoherent communication signals reflected off a scene, wherein the scene signal is received by a receiver array including a plurality of receive modules, and wherein the plurality of incoherent communication signals are spatially and temporally incoherent at a point when reaching the scene;
• constructing a reconstructed scene based on the scene signal reflected from the scene by:
• determining a scene visibility based on the scene signals;
• identifying a sampling function;
• calculating a sampled visibility based on the scene visibility and the sampling function;
• and
• performing an inverse Fourier transform of the sampled visibility to construct the reconstructed scene;
• and
• displaying the reconstructed scene on a display screen.
