My underlying thought is state of art planes can beat beat state of art missiles heralded at it by further than 40 kms, at which distance planes both planes would be glowing red in each others screens ... So what difference does it make in operation to have a 180 km radar vis-a-vis a 120 km radar.
Once we have decoded this I would like to make a it a little more complicated. Suppose we are hunting in formations (almost always the case) ... with the upgraded Su-30 radars, one would be able to look quite far indeed and nobody is going to shoot off missiles from 100 kms away ... so there should be enough warning before hand.
So my basic question is simple, given today's status quo what is the point of going on and on about how far my radar can see when I can't do anything at that distance, except taking a U-turn before I light up the enemy radars?
I'm under the impression you think to much in absolute terms. Say your radar x has 180 km vs. 5sqm target. Radar y has 120 km vs the same target. Now reduce the signature size auf your target. Radar X now can track it at 60km, while radar y is reduced to 40 km range. Quite a difference.
Plane x doesn't defeat missile y at range z. I thas a chance to do so. And not all targets are of the same quality. Reduced radar range just limits your choices. And since assets like AEW aircraft are a limited resource I can't embrace the idea that onboard sennsors are not necessary. If that where the case, Raptor and JSF wouldn't be fitted with large powerful radars.
Marc, you just made the RCS of the target 1/3rd at a swoosh. Tracking range is a fourth power of RCS. For making an aircraft undetectable by 3 times, you have to reduce its RCS by 81 times. And this is for a clean aircraft.
Modern aircraft have the same RCS as the armaments it carries. So as long as we do nothing for weapons' signature reduction and they are slung outside of the plane, even if you make the RCS of the plane 0, your total RCS will remain half of what it used to be. In that case you will reduce the distance at which you get detected by 16%.
