1. A method, comprising:
receiving, by an access point, pulses in a dynamic frequency selection (DFS) channel of the access point;
determining, by the access point, characteristics of the pulses;
processing, by the access point, the characteristics by performing a burst frequency probability distribution operation to ensure the pulses are distributed relatively evenly amongst available electromagnetic frequencies of the DFS channel;
varying, by the access point, a threshold value of the pulses for radar detection based on the processing of the characteristics; and
determining, by the access point, whether the pulses are radar, wherein the access point uses at least one of the characteristics and the varying of the threshold value to determine whether the pulses are radar.
