本文提出了一种结合双向测距（TWR）和被动测距方法的通用方法，称为主动-被动双向测距（AP-TWR）。所提出的方法提供了一个广泛的定位系统中的锚配置的通用解决方案。定义有源-无源和仅无源锚角色的可能性允许缩放系统以改善测距估计的均方根误差（RMSE）和空中时间占用。实验结果表明，与采用6个锚节点的单边TWR方法相比，采用5个主被动锚节点和1个被动锚节点的方法，RMSE提高了7.4%，空中时间占用率提高了12.5%.此外，仿真结果表明，一个最大的理论RMSE改善31.7%，可以实现与建议的设置。
This paper proposes a generalized approach combining two-way ranging (TWR) and passive ranging methods, called active-passive two-way ranging (AP-TWR). The proposed approach offers a generalized solution for a wide range of anchor configurations in positioning systems. The possibility to define active-passive and passive-only anchor roles allows scaling the system to improve the root-mean-square-error (RMSE) of the ranging estimations and the air time occupancy. Practical experiments show that with the proposed method consisting of 5 active-passive anchors and a single passive anchor, the RMSE is improved by 7.4% and the air time occupancy by 12.5% as compared to the single-sided TWR method with a 6 anchor configuration. Moreover, simulation results show that a maximum theoretical RMSE improvement of 31.7% can be achieved with the proposed setup.
