Abstract: A network device is disclosed for determining whether a received signal includes a radar signal. The network device can determine a beginning of a pulse within the signal as the time instant at which a power level of the signal exceeds an upper threshold. The network device can determine an end of the pulse as the time instant at which a drop in the power level associated with the signal exceeds a power drop threshold. The network device determines whether the pulse is part of the radar signal based, at least in part, on the beginning of the pulse and the end of the pulse. In some embodiments, the network device may cancel a DC offset from the signal prior to determining whether the signal includes a radar signal.
