No .. it does not require anything. Just the LOBs. It gives line witch fits the LOBs best. Now if there is no best solution (parallel LOBs for example) it gives no solution. If the LOBs are poor, or if the target changes course, even the best match will be rather loose.
But if you have good LOBs, after a leg, or LOBs from same time (let's say towed array and hull array for a sub), it should give good data, best possible in fact.
I guess it must be used on real subs. It is also said in Submarine by Clancy that Brits use automatic TMA all the time. So I wonder what this automatic TMA is.
Now I'm pretty close to have it working (or finding out I have it wrong
).
