Embodiment

[0028] A fast specific ship target recognition method based on satellite-terrestrial integration proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Such as figure 1 As shown, this process is the main workflow of a fast specific ship target recognition method based on satellite-ground integration. That is, joint processing on the ground and on the satellite. First, the black and white lists are obtained through the large data results of the AIS information processed on the ground; then the satellites use the black and white lists to identify specific ship targets in real time. At the same time, the uncertain information monitored by the satellites can be closed-loop fed back to the ground. Processing, adding ground database samples; finally, using the existing investigation process on the ground to add information to the black and white lists.

Abstract

The present invention relates to a kind of fast specific ship target identification method based on satellite-ground integration in the field of satellite identification technology, comprising the following steps: A: the ground system utilizes the AIS information accumulated for a long time, and is oriented to demand, and establishes the ordering of the importance of troubleshooting conditions; B : Enter AIS information, generate black and white lists according to the black and white list generation process; C: send the updated ship target black and white list to the satellite through the remote control channel, and the satellite performs real-time screening on the AIS information received in real time, and distributes the results to User terminal; D: Send the undeterminable AIS information received by the satellite to the ground system, use the black and white list generation process, and supplement the black and white lists. The invention effectively solves the problem of satellites selecting specific ship targets, and improves the discovery rate and accuracy rate of satellites for various specific ship targets.

Description

technical field [0001] The invention relates to the field of satellite-to-specific ship target recognition, in particular to ship target selection and classification using historical and real-time AIS information, and in particular to a fast specific ship target recognition method based on satellite-ground integration. Background technique [0002] The Automatic Identification System (AIS) is a communication system that uses the VHF maritime mobile frequency band communication protocol to exchange navigation data. AIS information includes ship dynamic information, manually input static data (ship length and width, etc.) and voyage-related data (ship draft, destination port, cargo, etc.). According to the regulations of the International Maritime Organization, all ships of 300 tons and above engaged in international routes, cargo ships of 500 tons and above engaged in non-international routes, and passenger ships regardless of tonnage should be equipped with AIS equipment.
