1. A system for detecting a RADAR signal in a communications network which utilizes signals different from the RADAR signal, the system comprising:

  • a receiver for receiving a first pulse;

    a self-correlator for measuring a self-correlation of the first pulse with a non-zero time offset copy of the first pulse;

    a comparator for comparing the self-correlation measurement with a threshold that is set from expected correlation of receiver noise; and

    a detector for determining that the first pulse is a RADAR pulse when the self-correlation measurement is lower than the threshold that is set from expected correlation of receiver noise.
