The magnitude of the maximum pulse loading situation within the STLM was reinvestigated. It was assumed that the victim transponder previously defined as El Monte in the STLM is replying at its maximum rate of 5000 pps. The uplink interrogator loading was calculated at distances of 22, and 7 nmi. The interrogator at 22 nmi was in the narrow band mode. At 7 nmi the interrogator was wide band. Beacon transponder squitter rates of 700 and 1350 will be used. The results reflect two types of pulse loading interactions Undesired interrogations at a transponder from aircraft operating in a different service volume but transmitting on a frequency within the victim transponders receiver bandwidth air to ground loading. Undesired replies and squitter received at an interrogator from a transponder servicing a different service volume but transmitting on a frequency within the victim interrogators receiver bandwidth ground-to-air loading.
