Need some advice.

I'm working on making some major adjustments to DW's radar/ESM model, including reworking detection curves for radars, adjusting ESM and radar antenna heights, etc.

I've found that when ESM antenna height is adjusted, detection ranges against seaskimmers can go out beyond 20nm*. I've looked at the equations and I think this is appropriate, but I wanted to run it by people in the know before I get too excited. Assuming that it's right, and I think it is, this means that DW has quality built-in equations for radar horizon that has been tucked away where we rarely get to see it, thanks to artifically limited ESM/radar ranges. I'd like to start unlocking the potential of the radar/ESM model in the NavalSimEngine.

So, I'd like to ask if you could steer me in the direction of any ballpark/non-classifiied figures for radar and ESM performance, especially for missile seeker heads (I've already found pretty good information for naval search radars thanks to the Naval Institute Guide on Google Books, and ballpark figures for aerial maritime surveilance radars from OneShot--but a 2nd opinion never hurts.). Right now my thoughts on ESM are to try to tweak the sensitivity so that counterdetection of an active seeker occurs somewhere around 2-3x the seekers' range. But the performance of various missile seekers is a bit of an enigma, since DW gives all missiles the same seeker--one that sees a skiff at 9km and an aircraft carrier at 18km--and that's really all I've known.

I'm not going to create individual seekers for every missile, but I would like to break them up in to families, e.g. 1st generation high-diver, 3rd generation sea-skimmer, etc.

Any thoughts?


*In-game results vs. ASCMs using the "missileskim30" doctrine (which I believe means the missiles cruise at 30ft) were 27km for a 10m mast (Osa), 39km for a 30m mast (Luhu), and 39km for a 35m mast (DeGaulle). A little longer than they should be, but close.
