Patent attributes
Embodiments of the present invention provide a method, apparatus and system of radar detection. The method, according to some demonstrative embodiments of the invention, may include comparing an energy level of signals received over a wireless communication channel to a threshold; during operation of a processor, if the energy level is above the threshold, determining independently of the processor one or more time values related to said signals; and if the energy level decreases to or below the threshold, interrupting the operation of the processor to determine, based on the time values, one or more parameters of a detection time period during which the energy level was above the threshold. Other embodiments are described and claimed.
