Coordinated scheduling method for space and space heterogeneous earth observation resources for dynamic target observation

Abstract

The invention discloses a method for coordinated scheduling of air-space heterogeneous earth observation resources oriented to dynamic target observation. Transit time window, and the time when the UAV arrives at the missing position of the moving target are divided and merged; construct the potential area from the missing time of the moving target; initialize or update the probability and certainty of the grid; The optimal coverage algorithm determines the optimal coverage band of the satellite; the multi-UAV cooperative search algorithm based on the immune algorithm is used to formulate the observation plan of the multi-UAV, and the position of the moving target and the time consumed by the cooperative scheduling and the satellite and UAV are output. observation plan. The invention effectively reduces and solves the problem of coordinated scheduling of air-space heterogeneous earth observation resources oriented to moving targets, and shows excellent performance in the solution process.

Description

technical field [0001] The invention belongs to the technical field of remote sensing, and in particular relates to a method for coordinated scheduling of air-space heterogeneous earth observation resources oriented to dynamic target observation. Background technique [0002] With the increase of the number of earth observation satellites, the research on multi-satellite observation network networking technology has received more and more attention, and the problem of multi-satellite coordinated scheduling is one of the important research directions. Compared with the single satellite scheduling problem, the use of multiple satellites can make more full use of the satellite's observation capabilities, but it also increases the scheduling complexity 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 optimization prob...

Problems solved by technology

In the field of collaborative scheduling of space-time heterogeneous earth observation resources for moving target observation, some scholars have proposed to use observation resources such as satellites and UAVs to search for moving targets collaboratively. However, the relevant research is relatively insufficient and not deep enough.
