<p>The device has an amplifier (11) i.e. logarithmic amplifier, receiving a radio frequency signal and a restoring signal that represents an envelope of an input signal. A phase estimation module (50) estimates stability of a phase of the radio frequency signal, and is provided with an estimation unit that estimates the phase. An evaluation unit evaluates temporal stability of the phase of the radio frequency signal, where presence of characteristic pulse is detected according to given criteria when the phase is stable.</p> |
