Some demonstrative embodiments include apparatuses, devices, systems and methods of radar detection. For example, an apparatus may include a first detector component to detect energy over a wireless communication channel; a second detector component to detect a signal over the wireless communication channel, and to determine at least a classification of the signal as a radar-type or a non-radar type; a storage component to store radar detection information corresponding to signals detected by the second detector component, the radar detection information including at least the classification of the signal and one or more characteristics of the signal; and a controller to activate the second detector component upon detection of the energy by the first detector component, the controller configured to cause a radar-detection analysis of the radar detection information corresponding to a predefined time period.
