Problems solved by technology

[0004] For the cooperative detection of ship targets by high-orbit remote-sensing satellites, the resolution of the image sequence acquired by high-orbit remote-sensing satellites is not high, and usually the imaging time interval between high-orbit remote-sensing satellites and low-orbit remote-sensing satellites is relatively long. The correlation method is no longer applicable to the scenario where high and low orbit remote sensing satellites cooperatively detect ship targets

Abstract

The invention relates to a method and system for associating target tracks and point tracks of high and low orbit remote sensing satellite ships. The method includes: obtaining ship target track data of high-orbit remote sensing satellites, ship target track information of low-orbit remote sensing satellites, and AIS ship target track data; Cooperative ship target association of data; based on acquisition time alignment, low-orbit remote sensing satellite and AIS data cooperative ship target correlation; according to the high-orbit remote sensing satellite and AIS data cooperative ship target The cooperative ship target correlation results of AIS data, determine the high and low orbit remote sensing satellite cooperative ship target track and point track correlation results, and the high and low orbit remote sensing satellite non-cooperative ship target track and point track correlation results. The invention can improve the correlation effectiveness and improve the accuracy of ship target detection.

Description

technical field [0001] The invention relates to the field of remote sensing satellite ship target detection, in particular to a high and low orbit remote sensing satellite ship target track and point track correlation method and system. Background technique [0002] High-orbit remote sensing satellites are usually able to continuously observe the designated sea area for a period of time, with a wide imaging width and wide coverage of the sea area. Taking geostationary orbit remote sensing satellites as an example, they stay in the sky over a fixed area for a long time, and can quickly adjust the imaging monitoring area as needed. Rapid response to incidents and near real-time surveillance of key targets ideal for extended surveillance and rapid imaging visits. High-orbit remote sensing satellites can obtain image sequences of designated sea areas to extract track information of ship targets. The disadvantage is that the image resolution is not high, so it is suitable for lar...
