In one embodiment a circuit arrangement for disturber detection comprises an input (I) for receiving an input signal (In), the input being adapted to be coupled to an antenna (A), a receiver circuit (LNA, DEM) coupled to the input (I) which is configured to provide a demodulated signal (Env) as a function of the input signal (In), and a disturber rejection circuit (DRC) which is coupled to an output of the receiver circuit (LNA, DEM). Therein the disturber rejection circuit (DRC) is configured to provide a first signal (S1) indicative of a low energy disturber and/or a second signal (S2) indicative of a square envelope disturber, the first and second signals being provided as a function of the demodulated signal (Env) at respective outputs (01, 02) of the disturber rejection circuit (DRC). Furthermore, a lightning detector and a method for disturber detection are described. |
