无线电干涉定位系统突破了精确测距和定位技术对器件性能的高要求,在资源高度受限的无线传感器网络中具有很好的应用前景。文章针对现有文献对干涉定位系统性能分析方面存在的不足,选择干涉距离估计环节作为研究对象,通过仿真实验定量研究了相位误差分布、频点数量、频带间隔、搜索区间等因素对干涉距离估计精度的影响,不仅为无线电干涉定位系统在不同应用场景中的参数设置和性能优化提供了依据,也为硬件升级等系统结构改造指明了研究方向。
Radio interferometric positioning system has broken the high demand for device performance by precise ranging and positioning technology and has good application prospect in wireless sensor networks with limited resource. According to the existing problems in the performance analysis of interferometric positioning system, this paper chooses the interference distance estimation link as the research object and quantitatively studies the estimation of the interference distance through the simulation experiment, such as the phase error distribution, the number of frequency points, the frequency band and the search interval The accuracy not only provides the basis for parameter setting and performance optimization of radio interference positioning system in different application scenarios, but also points out the research direction for the system structure remodeling such as hardware upgrade.
