Uml活動圖是uml的重要組成部分，適用於系統動態行為建模和描述工作流，與uml的其他圖形工具不同，它本質上是非面向對象的，而且其本身並不成熟，仍在改進之中，特別是在工作流應用方面。首先， uml活動圖描述的是響應內部處理的對象類的行為， uml活動圖通常假定在整個計算處理的過程中沒有外部事件引起的中斷，也沒有時間的延遲，這就限制了uml活動圖對一些復雜過程描述能力。第二，現實世界業務過程涉及的對象數據十分復雜，但是uml活動圖的對象語義卻非常簡略，用戶基本上無法從uml活動圖中獲取關于對象數據的信息，也不能確定參與交互的對象的特徵。First of all, we bring forward the basic project of tadil, which adapts to combined operations. it is suggested to use tdma ( the abbreviation of time division multiple access ) as the working pattern and utilize the concept of mobile ad hoc network to construct the data link network. aiming at the impact of time delay on data link and the characteristic of cooperative combat under the command of director aircraft, this thesis applies a kind of kalman filtering algorithm in polar coordinates to compensate the error of time delay, and then does the transformation of target motion parameters to obtain the current information of target
