I programmed a server for a Radar System, to get the data, control the peripherals, process the data (window-function, fft, distance_calculation) and sending the data through redis or websocket to the server/client. Everything with Python, not single line C. Thankful of numpy and the other tools we have highly optimized functions on C level with a pythonic API. Fast enough for realtime processing. Currently only with a low sample rate of 120 kS/s on two channels.
Yes, I know a little bit about processing, but not everything. I never visited an university to learn this.
