Abstract:
1. For use in a wireless network, a method of identifying radar signals, comprising: collecting data at a central aggregation node of said wireless network, said data pertaining to pulses determined by wireless devices of said wireless network to be radar pulses; discarding duplicate portions of said data for a pulse determined by multiple of said wireless devices to be a suspected radar pulse; determining, based on remaining data after said discarding, if a radar sequence exists by identifying X successive repetitions of a given time interval between ones of said pulses in said remaining data subject to a maximum of Y missing pulses and within a tolerance of Z microseconds; determining if an additional time interval exists in said data when determining a radar sequence does not exist based on said given time interval; and if an additional time interval does not exist, incrementing said given time interval and determining if a radar sequence exists based on said incremented time interval.
