The J-10C shouldn’t be limited to one direction; it’s a three-sided phased array radar.

but do we know which version is mounted?
by the way you attached pictures of the KLJ-7A instead of the KLJ-10A
3 sided?
True
The KLJ-10A radar supposedly does not exist. The J-10C should have KLJ-7A anyways.
The j10ce has the klj 10a and the picture sakiko posted is how it looks like
It seems theres much varieties on both radar and plane.
The KLJ-7A have 2 different types: mechanical-AESA mixed early version, and solid 3-face AESA.These are shown in pics above.
The plane was equipped with different types of radars, too. Probably the early J-10C was with KLJ-7A(which varieties unknown). And late J-10C and J-10CE was with KLJ-10A. But lacking of files and evidence since these are kept military or commercial secret.
Repair J10C radar!!!
su30sm2’s radar have been available to lock targets in 4 to 8 o’clock. j10c also need a good radar to deal with Rafale and su30sm
