Research on Fast Deployment Algorithm for Ocean Environment Monitoring Based on Ship-Borne High-Frequency Surface Wave Radar

Abstract

Marine environmental pollution, particularly from oil spills, has garnered significant attention due to its irreversible damage to marine ecosystems. Ship-borne high-frequency surface wave radar (HFSWR) holds promise for long-distance, wide-area marine environment monitoring, enabling real-time surveillance of oil pollution on the sea surface. This paper utilises two sets of ship-borne HFSWR to swiftly deploy and monitor oil spill areas through optimal deployment planning, specifically tailored for addressing oil spill incidents in designated sea surface regions. First, this paper outlines the deployment model for two sets of ship-borne HFSWR, which is based on quadrilateral monitoring areas and circular deployment regions for transmitting and receiving stations. Then, this paper presents a traversal algorithm that operates under the minimum resource parameter limit, followed by a fast algorithm derived from geometric relationships with delineating the scope of application. Theoretical and experimental results demonstrate that the proposed algorithm significantly reduces the computational complexity of the traversal algorithm while maintaining high accuracy.
