The location method and accuracy analysis for bistatic systems

The bistatic system discussed in this paper consists of one transmitter and one receiver at different sites, in which the transmitter only emits radar signal, and the receiver measures range sum, azimuth and elevation angles. In this paper, the location method and position errors of targets are analysed. By analyzing the region distribution of target position accuracy (GDOP) in the controlled airspace, the location performances of bistatic systems is illustrated. In this paper, the location method and its position accuracy for netted bistatic systems is analysed. The algorithm WLS is used for data fusion in the netted bistatic systems. The location performances of netted bistatic systems is discussed and it is shown that the position accuracy is improved greatly in comparison with bistatic systems
