Abstract
A simple and efficient localization method for rotating objects is introduced. The estimation of the position is performed using only a continuous-wave radar with multiple receiving antennas. The method relies on the establishment of a linear relation between the interelement phase shifts and frequency, which is exploitable in the near-to-intermediate field. The method is introduced, and its independence with respect to the shape of the target demonstrated. Monte Carlo simulations are performed to study the variance of the proposed estimator. An experimental validation is carried out with a rotating cylinder and shows good agreement with simulations.
