Abstract

The invention provides a method for searching and identifying ships by using an active remote sensing satellite. The method comprises the steps of 1 searching a designated sea area of interest by using the active remote sensing satellite; 2 performing active remote sensing satellite on-board processing to give an attention sequence of ships; 3 carrying out beam scheduling and working mode switching by active remote sensing satellite on-board autonomous task planning, and carrying out active remote sensing identification on the concerned ship; and 4 after identification is completed, enabling the active remote sensing satellite to continue to search for the designated sea area of interest. The invention discloses the method for searching and identifying ships by the active remote sensing satellite. The ship searching probability can be improved by combining the two-dimensional searching capability of the active remote sensing satellite according to the size of an appointed concerned seaarea and scanning an appointed area for multiple times, and meanwhile, the active remote sensing satellite is guided to carry out active remote sensing identification on important ships by combiningon-board autonomous processing and multivariate information fusion capabilities.

Description

technical field [0001] The invention relates to the field of overall design of satellites, relates to the efficiency optimization design of an active remote sensing satellite on-orbit application mode, and in particular to a method for searching and identifying ships by an active remote sensing satellite. Background technique [0002] Active remote sensing satellites are equipped with multifunctional active remote sensing that integrates search and identification. They have the advantages of high station position, large coverage area, high positioning accuracy, and downward viewing, which is conducive to the search of small ships, which can significantly improve the situational awareness of ships. [0003] The Chinese invention patent with the application number CN201410026322.3 discloses a beacon system and search method for multi-target search on the sea surface. The system includes a beacon device connected to the sea surface target. The beacon GPS positioning unit for th...
