| Popis: | This paper presents a new Ultra-wideband (UWB) antenna delay calibration method which is based on the Asymmetric Double-sided Two-way Ranging (ADS-TWR) to get the precise information of distance measurement with different UWB devices. We use a similar derivation as ADS-TWR to build the objective function based on the antenna delay model. Then we use Particle Swarm Optimization (PSO) to optimize the objective function and get the independent antenna delay of each device according to combination of different devices antenna delay. Finally we use the least square positioning method to verify the performance of different calibration methods. The result shows that our method is effective to the distance measurement system and positioning system. Compared with rough calibration method and official calibration method, our proposed method greatly improves the accuracy of the systems. |
