tomographic image resolutions from wifi sensing

hello i would like to ask how to obtain tomographic image resolutions from wifi sensing and imaging using signals processing. thanks very much.

Welcome to PF.

If you have one wifi transmitter and multiple receiver antennas, then the image resolution will be a function of the spacing of the furthest apart antennas. Where λ is the aperture of the antenna array in wavelengths. The angular resolution in degrees will be approximately;
Resolution = 57° / λ;
That can be applied in the horizontal and vertical dimensions.
The antenna array will need several elements, variously spaced between the end elements, to resolve the lower spatial frequencies in the image.

I did a Google search on that phrase from your post, and got lots of useful hits. Have a look at the hit list to see if you can find what you are looking for:

2.4 GHz is 12 cm. Seeing below that poses a fundamental challenge. 5 GHz is twice as good.
