In order to inprove the tracking performances of some sensors and local nodes, the paper discusses the state estimation techniques in multilevel multisensor surveillance systems with feedback information. based on the single sensor kalman fitering equations with feedback information, this paper presents two - level centralized, distributed and hybrid track level fusion methods with feedback information in multicoordinate systems. in the different cartesian coordinates, several kinds of track level fusion methods with feedback information for three - level multisensor data fusion systems are proposed, in which centralized - distributed, distrbuted - distributed and hybrid - distributed estimation combination problems with feedback information are considered, and proves that two kinds of three - level estimation solutions with or without feedback information are optimal and equivalent in the form of the theorem. the simulation results show that the multilevel multisensor data fusion system can not only increase the global estimation acuracy of target but also greatly improve the tracking perfomances of some sensors and local nodes by using the feedback information
為了改善局部節點和傳感器級的跟蹤性能，本文研究帶反饋信息的多級式多傳感器系統中的狀態估計技術.在給出有反饋信息情況下傳感器級狀態估計解的基礎上，本文提出多坐標系中有反饋信息的兩層集中、分佈和混合估計方程.在不同笛卡爾坐標系中，本文提出了幾種帶反饋信息的三層多傳感器系統中的航跡級融合方法，其中包括集-分估計、分-分估計和混-分估計，並以定理的形式證明有、無反饋信息情況下的兩類三層狀態估計是價的、最優的.模擬結果表明，在多傳感器信息融合系統中引入反饋機制可以明顯改善一些局部節點和傳感器級的跟蹤精度
