There are two more AESA panels behind of Gürz
I know there are 4. They are for 360degree real time coverage. But Gökdeniz at the back of the frigate so rear panels are useless.
2 plates could give 180 degree realtime coverage for Gökdeniz which positioned at the back.
Edit: MAR-D is very powerful radar which consumes too much electric power for a autonomous CIWS. Retinal Radar is enough for Gökdeniz.
Edit2: if currently it is impossible to connect fixed plates, then let's make MAR-D antenna swinging thus you wouldn't waste half lifespan your expensive AESA antenna.
Or change the geometry of antenna like RAVEN AESA
Or make it like fighters radar antenna
Long in short: instead of circular scan, Gökdeniz CIWS on the i -class and Barbaros class must have sectoral scan.
