The Type 381 was one of the first Chinese naval 3D search radar employing FRESCAN (Frequency Scanning) technique developed by the Nanjing Marine Radar Research Institute / No. 724 Institute. Initial versions were deployed on Jiangdong class FFG and Luda command variant class to provide long range surface search.
The original version (Sea Eagle C) won the 1987 First Prize of the National Science and Technology Progression. A enhanced variant (Sea Eagle C-B) with dual band back to back canted antenna similar to the Russian 'TOP PLATE' radar have been introduced, with designation as Sea Eagle S/C.
