Abstract

According to an example aspect of the present invention, there is provided a method comprising, determining an initial set of measurement results, wherein said initial set of measurements results comprises at least angles-of-arrivals and phases of initial reflected signals, the initial reflected signals being reflections of initial signals transmitted by a radar in a field of view of the radar, determining a phase map of the field of view of the radar, wherein the phase map comprises at least phase differences between the initial transmitted signals and the initial reflected signals as a function of said angles-of-arrivals of the initial reflected signals and determining a vibration map of the field of view of the radar based at least on the phase map.
