As mentioned above, the SAR information is collected at a longer period than the radar information. Therefore, in the time zone in which the SAR information is not collected, the position of the ship identified from at least one of the radar information and the AIS information is corrected based on the acquisition time of the radar information. Accordingly, the integrated vessel monitoring apparatus according to the present invention has an advantage that the vessel can be monitored without interruption according to time. The radar vessel position correcting means 132 is for correcting the position of the ship identified in the radar information. In the satellite mode, the radar vessel position correcting means 132 corrects the position of the vessel identified in the radar information based on the acquisition time T of the SAR information Can be corrected to the predicted position, which is a position at which the ship is expected to be positioned at the reference acquisition time (T).

In addition, the radar vessel position correcting unit 132 may calculate the predicted position using a Kalman filter.

The AIS ship position correcting means 131 is for correcting the position of the ship identified in the AIS information and corrects the position of the ship on the basis of the acquisition time of the radar information or the acquisition time T of the SAR information do.

In addition, the AIS vessel position correcting unit 131 corrects the position of the ship identified in the AIS information at a specific time when the radar information, the SAR information, and the AIS information are all acquired, To the position expected to be located at the same time as the acquisition time of the information or the acquisition time (T) of the SAR information.

In the real time mode in which the SAR information is not collected, the AIS vessel position correcting unit 131 corrects the position of the vessel identified in the AIS information at the same time as the reference acquisition time (T) based on the acquisition time of the radar information It is corrected to a position predicted to be located.

In the satellite mode in which the SAR information is collected, the AIS vessel position correcting unit 131 corrects the position of the vessel identified in the AIS information at the same time as the reference acquisition time (T) To be predicted to be corrected.

At this time, the AIS vessel position correcting unit 131 extracts the position, velocity and path of the ship from the first AIS information obtained from the AIS information acquired before the reference acquisition time T (T-1) The position, speed and path of the ship are extracted from the second AIS information obtained from the acquired AIS information (T + 1) after the acquisition time (T + 1), and the position of the ship expected to be located at the acquisition time is calculated.

Since the ship position correcting unit 130 may generate a time difference between the actual present time and the obtaining time of the SAR information, the SAR position correcting unit 133 for correcting the position of the ship identified in the SAR information may be further provided .

In addition, the SAR vessel position correction means 133 may be provided to correct the position of the vessel using the AIS information, and may correct the position of the vessel to a position predicted to be located at substantially the current time on the basis of the AIS information. .

Here, the SAR vessel position correction means 133 extracts the position, velocity, and path of the ship from the AIS information collected before the acquisition of the SAR information, and calculates a predicted position estimated to be located at the acquisition time of the SAR information And to correct the position of the ship identified in the SAR information to the predicted position. In addition, the SAR vessel position correction means 133 can correct the position error generated by the Doppler effect by correcting the position of the ship identified in the SAR information.

At this time, the time at which the radar information, the AIS information, and the SAR information are acquired is different, so that all the information may not be obtained at the current time to integrate the respective pieces of information. Therefore, the ship information integrating unit 140 integrates at least two pieces of information of the radar information, the AIS information, and the SAR information, which have been corrected in the ship position correcting unit 130, to generate the integrated ship information. For example, if the ship integration monitoring apparatus is in the real-time mode, the ship position correcting unit 130 integrates the corrected radar information and the AIS information to generate integrated vessel information. When the integrated vessel monitoring apparatus is in the satellite mode , The integrated vessel information can be generated by integrating the radar information, the AIS information, and the SAR information, which have been corrected by the ship position correcting unit 130.
