Are there cameras that see microwaves?

There are cameras that can see infrared and ultraviolet, what about microwaves and other wavelengths?

If we had a camera that only images microwaves for example, could we see wi-fi and Bluetooth as they reflect off surfaces?

What are the main limitations of building something like this? Is it the size difference between wavelength and sensor size?

You have. It isn’t a camera but a X-Y table with probe and spectral analyser. By scanning you can create image of different frequencies
