In response to the problem of minimizing the batch requirements for imaging satellites, this paper proposes a requirement coordination method for imaging satellite that considers temporal and spatial similarity. Firstly, the similarity of imaging satellite requirements was defined from the perspectives of observation time, target location, and remote sensor type. On this basis, combined with the imaging characteristics of point targets and area targets, an integrated method for imaging satellite requirement merging, requirement integration, and requirement conflict processing of point targets and area targets was designed. Finally, based on the prototype system verification, it was found that requirements has been greatly reduced through requirement coordination, which helps to achieve optimal utilization of satellite resources.
