The aerospace cooperative planning model for maritime moving target continuation observation

Abstract

Continuous observation on moving targets at sea has important implications to maintain the safety of the navigation barrier. Existing methods either rely on satellite observations, or only rely on UAV observation, did not solve the problem of continuous observation of the maritime moving target. On the basis of analysis of the current methods, we constructed the aerospace collaborative continuous observation model for moving target at sea, and put forward aerospace collaborative continuous observation strategy (ACCOS) to reduce the complexity of solving the model. ACCOS extracted five sub problems to solve the problem: Satellite planning, UAV flight plan, UAV observation sequence, target potential area and distribution probability density prediction, UAV path planning. In order to realize the optimization goal of the model, the five sub problems are modeled and solved in turn. Finally, the simulation results show that the proposed method can greatly reduce the average observation period of the target, and effectively solve the problem of the continuous observation of the moving target in the sea.
