Hello, quote:
ORIGINAL: dillonkbase I have a few questions about the uncertainty areas discussed above. I was wondering why after shrinking do the areas of uncertainty increase on land based targets... because they are moving or are _capable_ of moving. Remember, the uncertainty area is an estimate of where the target may be located. quote:
I know some targets are mobile but even when I have jstar's up in the Serbian mission I see wild swings in uncertainty... What is "the Serbian mission"? quote:
my thoughts: aren't moving sam TELs easier to spot on radar than non mobile sam TELs. Yes, they are. The uncertainty area is not simply about the fuzziness of the initial detection, it's about the ever-expanding area that the contact _may_ have move to since you last detected it. quote:
And if the target isn't moving shouldn't the uncertainy just continue to get lower, without "spikes" of higher uncertainty. See above. The longer time has passed since the last detection, the larger the uncertainty area will grow. quote:
It seems like instead of focusing on the area of uncertainty and refining the fix the computer just gives me the most recent sweep. I'm no expert on this but I feel like if I have elint surveillance from three widely different angles in the form of u2s, jstars, and E2 I should be able to get some pretty good fixes, especially as time passes. The problem with ESM/sonar readings on a _moving_ target is that at some point rh eolder uncertainty areas become useless as the contact moves completely out of them. So you are forced to rely on the most recent sweeps only and these may not be the most accurate. Again, a lot depends on how old your contact is. If you got a spike 2 hours ago and nothing since, don't hope for high accuracy. quote:
As for ships and aircraft, It also seems to take forever to gather speed and heading info, which once again I sort of wonder about. TMA is both an art and science, and while the principles are simple the application is _very_ tricky. quote:
One thing I would like to know is how search from multiple directions is combined? is triangulation happening? Yes, among other things.
