Innovative Applications of HF Radar (Second Edition)

Dear Colleagues,

This Special Issue is the second edition of the Special Issue “Innovative Applications of HF Radar”. After the resounding success of our first edition, we are thrilled to open the second edition. HF radar, including both HF surface wave radar and HF skywave over-the-horizon radar, is primarily employed for detecting and tracking maritime targets as well as monitoring sea state parameters like ocean currents, wind, and waves. HF radar boasts advantages such as wide coverage, long-range, and real-time monitoring capabilities. It has found extensive applications in diverse fields, including maritime security, maritime traffic and fishery management, and maritime disaster monitoring, thereby contributing to the safeguarding of maritime interests and the safety of maritime activities. Additionally, HF radar can be employed to monitor oceanic dynamic processes, including oceanic circulation and mesoscale eddies as well as oceanic disasters like typhoons and tsunamis. In recent years, a variety of new HF radar systems, such as bistatic HF radar, ship-borne or buoy-based, sky-wave transmitting and shore/ship-receiving systems, and MIMO systems have emerged, further expanding the detection range and application fields of HF radar.

In this Special Issue, we would like to focus on the innovative applications of HF radar, particularly those related to various new HF radar systems that have emerged in recent years. These innovative applications encompass not only new investigations directly related to target detection and sea state inversion with HF radar, but also research on signal processing and data quality evaluation of HF radar products. Additionally, we also aim to explore the new applications of HF radar in different industries and various application environments. This includes investigating how HF radar can be utilized in fields such as maritime surveillance, coastal management, weather monitoring, and environmental monitoring. By delving into these innovative applications, we hope to reveal the versatility of HF radar technology and its potential to address challenges in a wide range of sectors and settings. Moreover, through the study of these innovative applications, we strive to further explore the untapped potential of HF radar technology and expand its application fields in the realm of ocean remote sensing.

Articles may address, but are not limited to, the following topics related to HF radar:

• New HF radar system;
