Where did you get you info? How reliable is it?
I think it's hard to guess what it actually uses. The evidence on the PDE was based on accounts of the contrails and a quick popping noise made by
an aircraft. My understanding of PDE though is that you have to get up to 100+ detenations a second for it to be powerful enough and efficient
enough. Imagine being a pilot and getting thumped every second at a thrust output that would get you up to and at Mach 6, let alone the fatigue it
would put on the aircraft.
If you look at the current state of PDE and ramjet by companies etc. that are putting a TON of money into these projects, I find it a little hard to
believe that it was working over 10 years ago. The payoff for getting either of the technologies working would be/will be enormous.
If you look at everything we have technology wise, the one technology that we lack is an air-breathing engine that will get an aircraft into orbit.
It's highly possible that it was this technological shortcoming that led to the demise of the program.
