Study Of Single Base Station Positioning Algorithm Research And Localization Of AOA Based On UWB Signals

When we discuss Based on ultra-wideband (UWB) localizationtechnology， we could not avoid the error that from the Multipathpropagation、Multiple access communications、NLOS error and Signalcharacteristic of a number of factors make the Measuring value AOApositioning Arrival time TOA localization Arrival time difference TDOAlocation. So my thesis propose a new algorithm. It is a kind of Hybridlocation and Angle AOA positioning algorithms improve which on accountof single base station.In the first place, my thesis introduce the UWB researchbackground、definition、dominant position、channel model and the algorithm.Then discussion In-depth who can influence it and how to appraise it. Atthe same time the thesis account the AOA、the time and the time difference.Secondly, my thesis introduce a new way to calculate the Angle AOApositioning. In the "four A" channel model the new way can make it better.Thirdly, my thesis introduces a TOA/AOA hybrid location algorithm.It is from Kalman filtering Hybrid location. Because Kalmanfiltering tracking characteristics, two kinds of arithmeticsperformance in an especial circumstance. That can make it better.Finally, my thesis introduces a new system whitch use a aerial arrayas a reference station. Then, use the distance between meterage stationand mobile station as the amplitude. Get the mobile stations location withthe angle.
