I’m confused…I thought the lua looked more like this…

Oh…that’s luau…my bad.
That would make sense. A combatant will have a surface search radar and an air search radar or a combined surface/air search radar. (Kuznetsov is combined) From what you have shown in the data base, they only describe a “carrier search radar” in the sensors.lua. So, I would assume they are using the Kuznet’s combined surface/air search radar.
All radars are limited by Pulse repetition frequency (PRF) which dictates their maximum range or the radar horizon (plus thermal ducting) which determines the distance/range a radar can see a target given the height / altitude of that target above sea level.
(For those playing at home the formula is D≈3.57 x (√hr + √ht) where D is the distance the radar can detect a target in km; hr is the height of the radar in m; ht is the aircraft’s altitude, also in m; 3.57 is the metric constant for the earth…Pythagoras was a smart dude.)
The max range for Air search radars is mostly limited by their PRF for aircraft at medium to high altitude. The radar horizon formula comes in for aircraft flying at lower altitudes. You work the formula above, plugging in the aircraft altitude for ht. So an aircraft at 500m may not seen on radar if it is far enough away.
Just from the range rings shown, it looks to me like they may have correct max range correct for Kuznetsov. (PRF limited - we will assume the ring is correct because we will not get the PRF from an unclassified source.) The aircraft are at 26,000 ft and the Kuznetsov’s radar is situated pretty high. So the limiting factor is likely PRF not radar horizon. Just eyeballing it, I’d say it looks fairly correct for Kuznetsov. The Kirov and Slava? Need to take a look at the height of their radars and run the math.
Probably. Pretty cool if they are simulating that.
Now that @near_blind has me thinking…I’d be interested if they take radar horizon detection ranges into account against other ships…
While ships sail around at 0 ft AGL/MSL, their superstructure and masts can be several/many meters from sea level. We use mast height for ht, and run the formula to see the max-radar horizon limited range that ship can be seen on radar from another ship (call it the source ship), using hr for the source ship’s radar height.
Bigger target ships typically have higher ht values. Smaller target ships-lower ht values. The “armed speed boat” in DCS should have a fairly short detection range.
The range will remain constant for any given target-source ship pair, so it gives you a standard detection range for mission development.
