Topology reconstruction method of multi-domain unmanned system under topology attack

The invention relates to a strategy game-based dynamic redundant structure topology reconstruction method for a multi-domain unmanned system. The invention discloses a topology reconstruction method of a multi-domain unmanned system under a topology attack, which comprises the following steps of: acquiring a distributed interaction state space model of the multi-domain unmanned system through multi-sensor information of a heterogeneous multi-domain unmanned system under the topology attack, and designing a distributed extension topology node attack state observer on the basis of the distributed interaction state space model; by optimizing an estimation error value, designing an optimal observer gain and obtaining a topological node attack estimation value, the topological node attack is compensated by utilizing the design of a controller, and the network node state information cherishability of the multi-domain unmanned system is improved; furthermore, a topological transformation strategy execution set of th
