@Picdelamirand-oil what the true range of RBE2-AA Aesa say against 1m2 target ? and how good is meteor third party target engagement capability compare to AIM 120 ?
It is very hard to give a performance for an AESA radar, because the main characteristic of such a radar is the versality of all its technical characteristics. This means that it can adapt in real time to optimize its performance according to the conditions of the moment.
For example, it will do a time management: it will update all known tracks by going from one to the other directly without scanning all the space, and then it will use the remaining time to search for new tracks in the sector assigned to it.
When it updates the known tracks it will send for each track just the energy it needs to detect it in order to be as discrete as possible, and for the same reasons this energy will be spread out in time (the return will be compressed) and frequencies (the radar receiver will be able to reconstruct the signal).
After in search mode there is no reason to favour one direction rather than another and the energy sent will be more or less constant.
All that to say that in search mode for a sector in azimuth from -70° to +70° and a sector in site from - 60° to + 60° the range of detection on a target of 1m2 is 160 km. But on US plane generally the performance is given for -60° to +60° in azimuth and -14° to +14° in site! So they're sending more energy in each direction on average.
But once a target has been detected, the Radar will process it in known track update mode and adapt the energy it needs to be sent to detect it again. For example, if an F-35 opens its weapons bay doors to fire a missile, and is therefore detected by the Rafale, then even if it closes its weapons bay doors the Radar will still be able to detect it.
The same approach allows to search in a direction where one has a passive detection (so usually without knowing the distance) and the radar has a mode where it leads by increasing the energy in the direction of the passive signal until it has a detection itself.
So it's quite difficult to really talk about its performance.
