Multi-mode ship target detection and identification system and device

The invention relates to a multi-modal ship target detection and identification system and device, the system comprises a database module, a data visualization module, a ship detection and identification module and a data processing module, the database module and the data visualization module are both installed at a detection point; the device comprises a floating ring, a sea wave power unit, an anti-inclination support and a snapshot assembly. According to the method, the SAR technology and the AIS technology are combined, the verification information of the ship can be obtained by pre-exchanging information between the ship and the detection setting, and if the ship verification information does not exist, the relay SAR ship detection unit is led out and is located at the edge of the protected pipeline, so that the detection and identification efficiency of the offshore ship is improved, and the detection efficiency of the offshore ship is improved. And meanwhile, the detection and identification range is
