1. A communication device for detecting radar in an environment of wireless devices, the communication device comprising:
a memory; and
one or more processors that are configured to execute machine readable instructions stored in the memory that cause the one or more processors to:
detect a radio frequency pulse, the detected radio frequency pulse reflecting a pulse characteristic;
compare the pulse characteristic with pulse characteristics corresponding to a plurality of detected radio frequency pulses that are stored in a deny list at the communication device;
when the pulse characteristic matches at least one of the pulse characteristics of the pulse characteristics corresponding to the plurality of detected radio frequency pulses, increment a pulse counter associated with the at least one pulse characteristic of the pulse characteristics and ignore the detected radio frequency pulse, the pulse counter being incremented each time the at least one pulse characteristic for the plurality of detected radio frequency pulses is detected within the environment of wireless devices;
when the pulse characteristic does not match the at least one pulse characteristic of the pulse characteristics corresponding to the plurality of detected radio frequency pulses, determine whether to add the pulse characteristic corresponding with the detected radio frequency pulse to the deny list at the communication device;
apply a decay value to a stored pulse counter associated with a stored pulse characteristic in the deny list at the communication device; and
when the stored pulse counter is less than or equal to a threshold pulse counter, remove the stored pulse characteristic from the deny list.
