The Type 517 radar is believed to be a A-band/VHF air search radar widely deployed on PLA-N surface vessels with 4 antennas in two crossed-brace supported pairs, one above the other, each pair mounted on each side of a single tublar support carried on the turning gear.
As it is similar to the Russian P-8 'Dolphin'/KNIFE REST radar which PRC manufactures and deploys for the HQ-2 surface to air system complex, it is believed that the Type 517 have similar capabilities and specifications.
The system is manufactured by the Beijing Leiyin Electronic Technology Development company (北京雷音电子技术开发有限公司).
