How long does the offline processing take? How well would this work for a moving vehicle (assuming there's no other sensors e.g. IMU)? What are they actually

  1. Dunno, but they’re working in MATLAB. 2. I would not expect that to work very well without an IMU, but you can do some pretty remarkably good odometry using wheel rotations, vision, and/or automotive radar if you’re dead set against using an IMU. 3. I think they were measuring instantaneous Doppler and integrating to get phase. They only looked in a 1 MHz passband, and they didn’t have a very directional antenna, so they must have been acquiring something pretty narrow-band compared to the full downlink packets.

    > 1. Dunno, but they’re working in MATLAB. Processing time would also be highly dependent on what the processing was done with and once the algorithm was established it could be ported to something less generic than Matlab. For example, an FPGA or ASIC for potentially quite short/low-power processing times in not a lot of volume.
