Which radar ?
If what you mean is that object supported by four flanges on the engagement radar. That perhaps a feed horn. Which i'm curious on why no more people asking. "why feed horn for an AESA radar ?"
Existence of feed horn on top of a supposedly AESA could only means two points :
1.The radar is actually PESA
2.The radar is what i speculated a "Hybrid" between AESA-PESA that works in different band and they were sharing common aperture.
The feedhorn is for the higher band (e.g mm wave) While the AESA may work in another band (e.g X-band). There of course no disclosure on the design but this one is my speculation :
The PESA part is a reflectarray while the AESA part is behind the reflect-array's reflector.
The SM appears to delegate the control function to another vehicle.. as there seems to be no crew control cabin as the previous Pantsyr.
