Electromagnetic interference mapping

A Python script does all of the signal processing: tracking in the camera stream, computing the RF power and generating an EMI heatmap. The I/Q samples could be used to recover a massive amount of information on the actual radiation: harmonics, power distribution, phase, circuit states, surges, 3D mapping…

With better computer vision algorithm and adequate graphical representations, this tool could give a unique EMI/EMC insight to engineers. This schematic shows how it works:

There is a lot of ressources providing information to make those antennas, for instance: interferencetechnology.com (article) or EEVBlog (video).
