I finally got some information on the surface search capability of Chinese DDGs. This is from
The PLA uses two types of Ukrainian designed radar and is co-developing a new phased array radar, very likely for the new No. 170 class destroyer. These radar will play a crucial role for the PLA Navy and the PLA Air Force. The first type of Ukrainian radar acquired by the PLA was the Kvant-Radiolokatsiya company’s Mineral-ME naval targeting radar. The Mineral-ME is used on the PLA Navy’s Sovremenniy destroyers and has been purchased to equip the new No. 168 and No. 170 class destroyers. Believed to be a passive radar, meaning it does not emit signals and just collects them, it has a 450km range and can simultaneously track up to 50 targets, while processing information from up to 200 targets. The Mineral-ME provides both guidance and data-link functions for the MOSKIT SSMs on the Sovremenniys and for the new SSMs to equip the two new PLA Navy destroyers.
from sinodefense:
"Four 4-cell launcher for the YJ-83 (C-803) sea-skimming, radar-homing anti-ship cruise missile system are installed behind the funnel. The YJ-83 is said to have a final approach speed of Mach 1.5 and a maximum range of 150km. It is noted that the YJ-83 onboard the Type 052B relies on a Russian-made Band Stand fire-control radar to provide target information, which would enable the YJ-83 to reach its maximum range of fire without relaying target information by the shipborne helicopter."
This should be equipped on 052B, 052C and 956.
