Azerbaijan are going to update its FOE and friend system based on Turkish technology. Turkey said they want to update Azerbaijani forces that both country can fight together with the same systems. I am sure, as soon as turkey develop its low and medium radar(which they have now and might sell to Azerbaijan) also AESA radar by 2016, Azerbaijan will receive them all.
Because of Russia also wants to sell army technologies to Azerbaijan and has control over Armenia to solve the Karabagh conflict, Azerbaijan mostly doesn't announce what they bought from Turkey if its strategic. Also, after Ukrain, the next target is Azerbaijan, and Thats why Turkish prime minister made his first trip to Baku by cutting his rest in ANtalya and flying to Baku. He made it clear that Turkey will not give up Azerbaijan. and Now they just update everything to the Turkish system so they both can fight together. Also, there is new shipbuilding facility in Baku(just constructed by 600 million $ investment) so Turkey also can build its quick ships for Azeri navy. Otherwise, Russia doesnt let any navy vehicle to Caspian sea through the river(the only way for ships to come to caspian from Black sea.
Those old technology radars can be an easy target for anti radiation drones or rockets(new technology) which is also called Harpy, so there is no need for that. Todays technology is LPI(low probability of intercept) that while its searching and targeting, others cant see it. Turkey is really developed in both technology, Thats why, Russians cant take a risk against Turkey or simply Azerbaijan.
