Abstract
Radar signals can be detected by a Wireless Local Area Network (WLAN) receiver by modifying one or more pattern matching attributes. In one embodiment, the pattern matching attributes are modified when signal pulses received by the WLAN receiver are determined to have an increased likelihood of being radar signals. In one embodiment, a frequency variance of received signal pulses is used to determine the likelihood of received signal pulses being radar signals. The frequency variance is based, at least in part, on frequencies of Fast Fourier Transforms of the received signal pulses.
