Type 517 radar is believed to be an A-band/VHF air search radar widely deployed on PLAN surface vessels with 4 antennas in two crossed-brace supported pairs, one above the other, mounted in pairs on each side of a single tubular support carried on the turning gear.
Similar to the Russian P-8 'Dolphin'/KNIFE REST radar which China manufactures and deploys for the HQ-2 surface to air system complex, it is believed that Type 517 has 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).
