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] like 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 invention relates to a rapid specific ship target identification method based on satellite-ground integration in the technical field of satellite identification, and the method comprises the following steps: A, a ground system using AIS information accumulated for a long time to establish a checking condition importance degree sequence for demands; B, inputting the AIS information, and generating a black list and a white list according to black list and white list generation processes; C, sending the updated ship target black and white list to a satellite through a remote control channel,carrying out real-time discrimination on AIS information received in real time by the satellite, and distributing a result to a user side in real time; and D, sending the uncertain AIS information received by the satellite to a ground system, and supplementing a black list and a white list by using a black list and white list generation process. According to the method, the problem that the satellite selects the specific ship target is effectively solved, and the discovery rate and accuracy of the satellite on various specific ship targets are improved.

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.
