ABSTRACT:
A method for detecting a signal having random characteristics. A plurality of bursts are detected within a predetermined time period. The plurality of bursts are evaluated to determine how many pulses each of the plurality of bursts contains. The signal having random characteristics is present responsive to the ratio of number of bursts containing a first predetermined number of pulses being approximately equal to number of bursts containing a second predetermined number of pulses. For signals such as a Bin-5 Test Signal, the signal is determined to be present responsive to the number of singletons (bursts having one pulse), the number of pairs (bursts having two pulses) and the number of triplets (bursts having three pulses) being approximately equal.
