You would be needing MW of power to effectively jam it and that's something a fighter jet doesn't have. Like the test against S-300 radar systems done many years ago in Greece and Slovenia resulted in nothing. Only known system able to be effective was a Il-76 built around jamming and it ended up jamming itself as well.
Not so simple. Rafale spectra did very well against slovak s-300. It depends on many thing like range, power or technology and methods used. Also a jammer will concentrate its energy a bit like an engagement radar while the early warning radar even if more powerfull will spread its signal/power to scan a greater area of the sky. At the end the jammer can end up with more power than the early warning radar.
It's not only a question of power. You can do it smart way.
But overall, it's a game where you need to constantly upgraded your database of enemy radar signals and use updated tactic/ algho for jamming.
Russian made their s-400 work in cooperation to triangulate Growlers because they are very good at jamming. Don't underestimate them.
That's the point I was trying to make. It doesn't. How can they even do that?
Apart from the impossibility of it where a fighter pilot is trying to jam an enemy aircraft using his EW system plus trying to fire a missile at it.
So if your EW system is active it's bound to interfere with the functioning of a missile that you are trying to fire.
Re aircraft take any aircraft you like. Take Rafale for instance. You are using SPECTRA's phased array radar jammer to interfere with the operation of radar of a hostile aircraft. And while you are at it can you fire a Meteor BVR air to air missile or even a SCALP cruise missile?
You can't because then the noise/false information being emitted from SPECTRA's phased radar jammer will blanket the sensors of the Meteor and the Scalp as well.
Modern fighter computers will know that the jammer is active and if the fighter launches missiles it won't jamm on their frequency. With datalink btw aircraft you can even be protected by friendly fighter's jammers, something already integrated in most russian jammer. Go see the ad videos on youtube.
Meteor has a datalink with the Rafale and it won't jamm it too because it knows it is it's own missile. Scalp uses inertial navigation with gps updates, spectra doesn't jamm gps and inertial navigation can't be jammed by an EW system.
A jammer in a fighter won't work alone. It is connected the main computer that acts like a battle management system. What you say is true for mirage, Mig-29, Su-27.... Modern system are far more smarter than you think.
