process transmitted and received signals provided by respective radar modules to establish measurement signals that are coherent in relation to each other; and
perform phase noise compensation, including:
determining variation between spectra corresponding to respective measurement signals by determining a scalar product of a first measurement signal spectrum and a second measurement signal spectrum; and
canceling a phase noise portion of a respective spectrum amongst the measurement spectra separate from determining a variation between spectra.
