Abstract： With the continuous support of Chinese High-Technology 863 Plan Project， marine environment monitoring technology by HF radar has formed a complete intellectual property system， and has begun the process of industrialization. Along with the development of marine resources， ecological and environmental protection， disaster prevention and mitigation strategies as well as the growing demand for defense， On one hand the precision of coastal ocean detection element should be enhanced， on the other hand， it also requires significantly improvement in distinct detection， to break though the pattern of coastal detection. This projects aims to establish a distributed over-horizontal high frequency surface wave radar （HFSWR） networks to monitor the ocean environments. It is made up of three land-based HFSWR systems working at two or more frequencies； the radars can also receive the radar echoes of other two radars. A high frequency sky wave transmitter is also synchronized by satellite to work together with the HFSWR to establish the integrated ocean environment monitoring network.This project also aims to achieve fine observation within 200 km off the coastline， and effective detection within 350 km. To carry out a standardized measurement test and to improve the accuracy of wind， wave and current measurements of HFSWR. And supply a key equipment for large area of the marine environment monitoring in China

Key Words： High frequency Surface Wave Radar； Skywave； Ionosphere Interference Suppression； Synchronous
