The invention discloses an offshore small target detection system and method. The system comprises a coast radar network, a seabed node network, an AIS information management center, a multi-source information fusion processor, a data management center and a display interaction center. The coast radar network is used for acquiring target information; the seabed node group is used for acquiring underwater acoustic signals and seabed seismic signals; the AIS information management center is used for carrying out information identification on a ship equipped with AIS equipment; the multi-source information fusion processor is used for preprocessing the received information and carrying out positioning, track fusion and track prediction on a target; the data management center is used for storing the uploaded data through a database; and the display interaction center is used for displaying information. Target trajectory tracking prediction can be carried out in a large range through an offshore small target detection system, the tracking quality of the target trajectory can be effectively improved, and the accuracy of target detection is improved.
Description
technical field [0001] The invention relates to the technical field of target detection, in particular to a small offshore target detection system and method. Background technique [0002] The coastal waters are vast, the environment is complex, and the early warning and detection capabilities are weak. For example, frogmen, unmanned ships, and small submersibles are hidden on the sea surface or on the seabed. They have a wide range of activities, ranging from the sea to islands and reefs. [0003] Although the current radar active detection technology can observe targets within its capabilities, it cannot detect and track some ships throughout the entire process, and it lacks target submarine activity detection information. OBN (Ocean Bottom Node, submarine node, which is a multi-component seismometer located on the seabed and can independently collect and record seismic signals) is deployed on the seabed in a network, which can monitor targets in the water and track them....
