Camera That Can See Radio Waves. Their method uses radio tomographic imaging (rti), which can see, locate and track moving people or objects in an area surrounded by inexpensive radio transceivers that send and receive signals. Radio signals, especially at low frequencies, are highly effective in penetrating walls.

The difference is a time delay in the phase of the wave. In a sense, we actually do build such cameras, and they are called radio telescopes, and they have reflector lens arrays that occupy acres of land. Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz and below.

At 30 hz the corresponding wavelength is 10,000 km (longer than the radius of the earth). This is a phenomenon caused by radio waves traveling around a surface and resonating. The difference is a time delay in the phase of the wave. It is well known that radio waves can pass through walls.
