Facing increasingly complex maritime rights situations, coastal security radar has become a core component of China’s all-weather maritime defense system. China has achieved technological breakthroughs in high-frequency surface wave radar and phased array radar, enabling over-the-horizon monitoring, multi-target tracking, and anti-jamming capabilities. These advancements strongly support the safeguarding of maritime sovereignty and the execution of maritime security operations.

China’s coastal security radar technology has evolved from importing and imitating to independent innovation. Key technologies such as high-frequency surface wave radar and phased array radar have significantly enhanced monitoring and anti-jamming capabilities, providing crucial support for safeguarding national maritime rights and coastal security.

As a critical equipment for safeguarding national maritime rights and interests, coastal security radar plays an increasingly vital role in the complex international environment. This article systematically analyzes its types, performance, and challenges, while also exploring future development trends with the deep integration of artificial intelligence. It aims to provide technical references for enhancing China’s coastal security capabilities.
