Dfs radar detection

A system comprising:

• a hardware processor;
• a memory;
• storing instructions which, when executed by the processor;
• cause the processor to:
• receive a plurality of bursts in a dynamic frequency selection (DFS) channel;
• store the plurality of bursts in a queue;
• in response to the queue comprising a threshold amount of bursts, determine a timespan of a first burst in the queue to a last burst in the queue;
• partition the timespan into at least a first group and a second group;
• determine a first number of bursts present in the first group and a second number of bursts present in the second group;
• in response to a difference between the first number of bursts and the second number of bursts equaling more than one, determine the radar is not present;
• and
• in response to the difference between the first number of bursts and the second number of bursts equaling one or less, determine the radar is present.

A method for determining presence of a radar;

• comprising:
• receiving, by an access point, a plurality of pulses in a dynamic frequency selection (DFS) channel, wherein the plurality of pulses are received by a first radio chain, a second radio chain, or both the first radio chain and the second radio chain;
• merging, by the access point, data about the plurality of pulses from the first radio chain and data about the plurality of pulses from the second radio chain to create a merged list of the plurality of pulses, wherein the merged list includes a source of the data about the plurality of pulses;
• identifying, by the access point and using the merged list, a potentially valid radar signal;
• determining;
• by the access point and using the merged list;
• whether each pulse of the potentially valid radar signal comprises a same source;
• wherein the potentially valid radar signal is determined to identify the radar when each pulse of the potentially valid radar comprises the same source;
• wherein the potentially valid radar signal is determined to not identify the radar when at least one pulse of the potentially valid radar signal does not have the same source.
