The Rafale is old tech and a dead end. The new radar keeps getting delayed, now pushed out to 2030's, obviously there are problems.
lol...Let me post what someone that knows more than you said.
"
RDY is a development for the RDI with a programmable signal processor. Originally Thompson-CST proposed the RDX, a version of RDY with the “RADANT” antenna. While Dassault electronic proposed Antilope-60 a PESA version of the Radar on the Mirage 2000N. Thompson one but due to how French competitions work Dassault got part of the work share. As a result RBE2 is mostly the RDX design but with Antilope-60’s transmitter. The goal of RBE2 seems to have been robust multimode capabilities and interleaving, that seems to be why they wanted a PESA. However development of the software proved to be very problematic, especially the air to ground modes. this seems to be why the Rafale F1 came about.
RDY-2 does have more robust air to ground modes but that is the UAE exclusive version and it came later on after RBE2 was in production."
