Frequency Estimation From Limited Samples: Nonlinearizing Time-of-Flight Radial Velocity Estimation

Abstract: Radial motion in indirect time-of-flight range imaging causes instantaneous frequency shifts in the data. Instantaneous frequency estimation is a well studied topic, but existing methods are either computationally inefficient, or require a minimum of several tens of samples to be accurate. Time-of-flight range imaging satisfies neither of these conditions, necessitating a new technique. Through differentiation, a differential equation of the instantaneous frequency is derived, transformed to a nonstationary or… Show more
