In wireless positioning environment based on Ultra Wideband Radio (UWB), as a result of the integrated influence of several disadvantages including multipath、non-line-of-sight (NLOS) propagation 、interference and channel frequency characteristics, the measurements of the features in TDOA, TOA, AOA inevitably get some errors, leading to the performance of all sorts of positioning algorithm dropping significantly. What’s worse, greater deviation of positioning estimation emerges.Centered on the core issue –improving the positioning accuracy, on the basis of multi-base station positioning algorithm as well as the advanced single base positioning algorithm, this paper conduct a deep research of UWB wireless positioning technology from four main aspects: analysis of the multi-base station TDOA positioning algorithm, anti-NLOS high-accuracy positioning technology,hybrid positioning algorithm, single base station positioning algorithm based on antenna array. |
