Aerospace heterogeneous earth observation resource collaborative scheduling method for static target observation

Abstract

The invention discloses a static target observation-oriented aerospace heterogeneous earth observation resource collaborative scheduling method, and the method comprises the following steps: in a task allocation stage, formulating a task allocation scheme and allocating the task allocation scheme to each sub-planning center; in the resource scheduling stage, enabling the sub-planning center to formulate an optimal resource observation scheme according to the resource capability and the task demand to plan the allocated task; distributing tasks which are not planned to a virtual sub-planning center, selecting three neighborhood structures by adopting a simulated annealing algorithm based on a dynamic neighborhood structure adjustment algorithm, solving an air-space heterogeneous earth observation resource collaborative scheduling problem, reformulating a resource scheduling scheme by the sub-planning center, and generating a final task distribution scheme and a final resource observation scheme. According to the method, a dynamic neighborhood structure adjustment strategy is introduced, the search direction of the algorithm is changed in time through historical search results, so the algorithm is guided to search in the direction of the optimal solution, the optimization performance of the algorithm is improved, and the convergence speed can be increased.

Description

technical field [0001] The invention belongs to the technical field of remote sensing, and in particular relates to a method for collaborative scheduling of space-time heterogeneous earth observation resources oriented to static target observation. [0002] technical background [0003] With the increase in the number of earth observation satellites, the research on multi-satellite observation network networking technology has received more and more attention, and it is one of the important research directions of multi-satellite cooperative scheduling problem. Compared with the single-satellite scheduling problem, the use of multiple satellites can make full use of the observation capabilities of satellites, but it also increases the complexity of scheduling and brings greater challenges to the satellite scheduling problem. The multi-UAV cooperative scheduling problem is similar to the multi-satellite cooperative scheduling problem. It is also a complex combinatorial optimiza...

Problems solved by technology

[0004] The research on the coordinated scheduling technology of multi-satellite and multi-UAV has become mature, but in recent years, the research on the coordinated scheduling technology of space heterogeneous earth observation resources is quite insufficient

Judging from the current research, most relevant researchers mainly focus on the information fusion of satellite remote sensing data and UAV remote sensing data. However, the remote sensing data fusion technology of heterogeneous resources has been relatively mature and has been widely used in related fields. , but the research on the collaborative organization mode of space and space heterogeneous earth observation resources for static targets and the corresponding collaborative scheduling technology is not enough
