面向海上移动目标的空天协同连续观测模型

由于视距限制,对海上移动目标进行连续观测与定位探测难度较大.现有方法通过卫星和无人机等单平台对目标进行观测,不能解决面向海上移动目标连续观测的问题.针对当前单个平台的不足,本文构建了面向海上移动目标的空天协同连续观测模型,并提出了空天协同连续观测策略.空天协同连续观测策略抽取出卫星规划、无人机飞行计划、观测序列、区域预测以及路径规划等五个子问题,并对其进行建模求解.仿真实验表明,该方法大大降低了目标的平均观测周期,有效解决了海上移动目标连续观测问题.

The aerospace cooperative planning model for maritime moving target continuation observation

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.
