Re: CHG/REPLACE: Additional Acronyms and SOSUS words/phrases

Jim,

I've enjoyed this trip down memory lane and have to admit as a short term (68-71) non-career type a lot of the terms are unfamiliar. But one term (Pinetree and Bathtub patterns) really stands out. Back in the day JOs were encouraged to write and submit a technical paper to COSL. Being a typical nerdy engineer (electrical) I jumped at the chance and submitted a paper describing (with lots of equations and plots) how those patterns were simply an artifact of passing broadband noise through a time-delay beamformer (the technical term is comb filtering). At the time I was upset that the "Principles of LF Analysis" text attributed the patterns to multipath effects - which have only one CPA. I guess the folks at WECO/Bell didn't bless my paper; it never saw the light of day to the best of my knowledge.
