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

Abstract

The invention discloses an air-space heterogeneous earth observation resource collaborative scheduling method for dynamic target observation. The method comprises the following steps: meshing a task area; carrying out the equidistant dispersion processing in the search process; carrying out segmentation and combination processing on the discretized rolling planning period point, the transit time window of the satellite and the time when the unmanned aerial vehicle arrives at the missing position of the moving target; constructing a missing time potential area of the slave moving target; initializing or updating the probability and the certainty degree of the grid; determining a satellite optimal coverage strip by adopting a satellite optimal coverage algorithm based on a discrete side-sway angle; formulating an observation plan of the multiple unmanned aerial vehicles by adopting a multi-unmanned aerial vehicle collaborative search algorithm based on an immune algorithm, and outputting the position of the moving target, time consumed by collaborative scheduling and the observation plan of the satellite and the unmanned aerial vehicles. According to the method, the problem of moving target-oriented aerospace heterogeneous earth observation resource collaborative scheduling is effectively solved, and excellent performance is shown in the solving process.

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 dynamic target observation. Background technique [0002] 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 optimization pr...
