Abstract:


    Doppler ToF imaging utilizes heterodyne modulation to measure the velocity from the Doppler frequency shift, which uniquely facilitates the instantaneous radial velocity estimation. This work extends the conventional D-ToF theory to arbitrary frequency, making it possible to find the optimal sampling and decoding method for simultaneous depth and velocity sensing.
