Radio Tomography Imaging

Since I conduct research on tomography area, I thought writing a small article as an introduction to many who does not know about this.

Radio Tomography Imaging (RTI) is a technique used to generate 2D images of the change in the electro-magnetic field inside the area covered by the radio transceivers to spot the presence and movements of animates (e.g., people,
large animals) or large metallic objects (e.g., cars).

Below are some graphs of the basic experiments I conducted to see this effect. I have plotted two plots per graph. Clear Line of  Sight (LOS) and a man standing in the middle(LOS) disturbing the link which allows us to see the difference clearly. Plot is for a single link, using many distances. Plotted graphs using matplotlib. Here is the link for the code.
