The invention relates to a method for testing the electromagnetic compatibility of a radar detector with at least one onboard pulse signal transmitter, wherein said radar detector and each onboard transmitter are part of the same platform, by means of eliminating the onboard component in the signals received by said radar detector, where the onboard component corresponds to the mix of the direct component and the reflected component onboard, said method comprising a training phase allowing the detected pulses to be divided into classes, grouping together the pulses for which at least two characteristics have a common range of values, and a phase of eliminating the pulses that belong to the selected classes.
