1. A method comprising:
obtaining, by a wireless device, a set of sensing values, each of the sensing values characterizing a signal of a set of signals received from an object located in an environment of the wireless device;
generating a plurality of covariance matrices (CMs), wherein each of the plurality of CMs is representative of at least a subset of the set of sensing values, and wherein a first CM of the plurality of CMs is associated with a first frequency increment of the set of signals;
determining one or more eigenvectors for each of the plurality of CMs; and
identifying, based on the determined eigenvectors, localization of the object in the environment of the wireless device.
