Abstract

The invention provides a method for searching and identifying ships by active remote sensing satellites, comprising the following steps: step 1, the active remote sensing satellites search for designated sea areas of interest; ; Step 3, active remote sensing satellite on-board autonomous mission planning, beam scheduling and working mode switching, active remote sensing identification of ships of interest; Step 4, after the identification is completed, active remote sensing satellites continue to search for designated sea areas of interest. The method for searching and identifying ships by active remote sensing satellites of the present invention can improve the search probability for ships by multiple scans of designated areas according to the size of the designated sea area of ​​interest, combined with the two-dimensional search capabilities of active remote sensing satellites, and at the same time combine On-board autonomous processing and multi-information fusion capabilities guide active remote sensing satellites to conduct active remote sensing identification of important ships.

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...
