quickly joe, i just wanted to say that you are right and i am wrong about aob being small at long ranges, i made a mission putting a target at max hydrophone range,
just making two different target courses showed me that range has nothing to do with aob at LR.

i havent worked on the magic bullet since last post, im not bankrupt for ideas, if one thing wont work something else might, and who said we need to make the calculation at long range,
i didnt, i said it might work, until i made that mission to test aob at LR, it was still an idea that MIGHT work, but it didnt, and im grateful for your input.
it may be that a map plot is the only way at LR, but again who says it has to be done at long range, that was just a thought, now proved to be wrong.
but until i can sit down, with some time to work on this problem, or someone else does, theories will abound, but be unproved, nothing wrong with that.
im not bankrupt for ideas, i would still like to determine target speed using that formula, and there must be a way to do it with the hydrophones, ill work on it when i can, and i hope to come up with some answer,
but i know one thing, it wont be aob at LR.
thanks joe, after reading your post, you forced me to check that idea out, now i wont waste time with a bad idea.
