How to classify contacts?

[el_gato]

So I'm back into in-depth (no pun intended lol) simulations. How I passed up this gem is beyond me. I guess I didn't get a good grip on what the game was going to be like through the initial advertising years ago.

~ Anyways ~

I used to play a lot of Janes F-18, Longbow, and F-15 so the naval stuff is a bit of a learning curve for me. I've read some good guides on how to find tracks, but really having a hard time classifying them.

Background information:
Typically I like to use / control MH-60, Orion, or the FFG. I play random Korean water missions and I typically drop DIFAR in a 2-3 mile spread and put on directional modes. I can find the contacts for the most part and use some active stuff if I feel I need to be a bit more sure, but what do I need to look at / do to classify the track?

Any advice would be great ~

Also I just installed what I believe to be the latest RA mod as well.

Cheers ~
