It needs a bit of filtering and frequency domain analysis, Fourier stuff, to extract the information you want, eg range, or speed, or imaging, and discard the stuff you dont. But thats mainly a software problem - theres now an analog output ready for the computer. Sure, I can do basic proximity detection and rangefinding at the bench scale with existing ultrasound or infrared sensors, but this is so much more interesting.
