Marty wants to know where study was published. The only publication I am aware of was a Technical Report to the US Army's Limited Warfare Laboratories in 1973. I used to have a copy and if I find it, can provide the document number, but if you're handy retrieving federal documents from their archive services it should be locatable. If its interesting, there were several EE's associated with this sudy, as well as Psychology PHD's (and one ABD). And, of course, appropriately qualified personnel from several selected federal agencies who had an interest.

Rick,

Thanks. Unfortunately, having only worked in the private sector, I'm ill equiped to search this. It's likely some others here could assist though. Being an EE by profession, I am most interested in how this was approached. Especially given the limited technology back then. These days the most sophisticated DSP is dirt cheap.
