针对信息栅格支持下的航迹合成中的资源利用问题，提出了一种以满足目标跟踪服务为目的的传感器资源协同选择策略。首先建立了以服务为驱动的航迹合成框架，然后利用基于协方差的目标跟踪精度描述服务需求，建立了信息栅格中资源协同选择的策略模型，最后给出了传感器资源选择的算法步骤，并进行了算法的仿真。仿真结果表明，该算法既能根据服务需求对目标进行跟踪，又能够根据目标跟踪精度动态调整进入融合中心的传感器资源，最大限度地降低对资源的使用。

A service requirement driven multi-sensor resource selection was proposed for composite tracking based on information grid.Firstly，the composite tracking structure based on service was established.Then，on the basis of describing service requirement using convariance，the coordinated selection model of composite tracking resource based on information grid was built up.A resource selection algorithm for composite tracking was presented here，and simulation was made to the algorithm.The simulation shows that the algorithm can not only track the target according to the expected service，but also adjust the resource of fusion center dynamically，thus can save much more resources.
