Method of detecting interference in a communication signal

A method of detecting potential interference of at least a radar signal in an incoming signal received by a wireless communication system, said radar signal being a pulse train defined by a pulse repetition period, called radar period, and by a pulse duration, this method comprising the steps of:

• obtaining a measurement of said incoming signal during a measurement duration proportional to a known pulse duration of a known radar signal;
• performing a first comparison between said measurement and a first threshold;
• counting the number of measurements exceeding said first threshold to generate a first count;
• performing a second comparison between said measurement and a second threshold if said measurement exceeds said first threshold, said second threshold being greater than said first threshold,
• if said measurement exceeds said first and second thresholds, performing conditionally an intermediate test to check if the incoming signal corresponds to a radar signal or to an unknown signal by using at least said first and second counts, and
• if the incoming signal corresponds to a radar signal, performing a final test to identify the radar signal among a plurality of known radar signals.
