With the further exploration of the ocean by human beings，the ocean has occupied an increasingly important position in the development of the country. How to comprehensively apply the sky-based means to obtain marine information and realize multi-base collaborative accomplishment of the maritime target mission has become particularly important. The system mainly combines space-based and space-based，and realizes the task planning of sky integrated ocean remote sensing resources to complete the identification and monitoring of maritime wide-area targets and moving targets. After the simulation experiment，the sky-based collaborative maritime target mission planning is completed，and multi-source remote sensing fusion is realized.
