Simple continuous tracking radar system with cantenna We are in need of a simple radar target tracking signal processing method. It's to be very short range, less than 5 meters. It needs to track a single target that can be moving or stationary at any time. We are using 2.4 GHz ISM band. Here is an MIT OCW site about the hardware that we have to work with on the RF end... MIT Online Courseware - Small Radar System We have the hardware all assembled and working right now. We have also purchased an Arduino MEGA 2560 for signal processing. We also have a video output device with which we made a couple of games the radar system will control. Kind of like a Playstation Move device, only using radar and probably much less functional. So what type of signal processing should we do on Arduino in order to provide tracking or ranging information? The target (a large metal-covered apron which the user wears) can be moving or stationary at any time. The range of detection only needs to be a few meters, nothing more. I've looked into some text about this and it seems its all geared towards outdoor use, crazy amounts of targets, etc. Can anyone direct me to some resources that have done this? If not, what would you recommend in terms of signal processing?
