Digital burst, not pulse transmissions, there is a big difference.
A burst transmission or data burst is the broadcast of a relatively high-bandwidth transmission over a short period. Burst transmissions broadcast a compressed message at a very high data signaling rate within a very short transmission time. This technique is popular with the military and spies, who both wish to minimize the chance of their radio transmissions being detected, a low probability of intercept and low probability of recognition. I seem to recall that this type of signal was developed in the late '70s and became widely used in the early '80s by the military. Anyone know more about the development curve?
Burst transmission - Wikipedia
Timing around the 80s with LPI (Low probability of intercept) and LPR (Low probability of recognition)
In Bennewitz's case it may have been short burst of analog? But as Chris indicated --> Pareidolia - Wikipedia
I don't think it would have been a huge mystery to the NSA (if they originated the transmissions) as to how he managed to recognize and detect these burst transmissions. It isn't as if we are dealing with VLPI/R ...lol "very low probability of intercept and recognition"
Edit: I would imaging this is a most basic form of transmitting sensitive information -- many levels down from encrypted transmissions -- it raises the question as to the real purpose not being what Doty claims (something reserved for highly classified transmissions).
