【摘要】：提出一种利用线性调频扩频技术进行通信并实现测距的方法,该测距方法能够适用于复杂室内通信环境的无线传感器网络节点间的测距。在三边测距定位的基础上,提出了四边测距定位算法,突破了三边测距定位的局限性。为了进一步提高精度,采用了求质心和加权质心的方法。实验结果表明,加权质心算法具有较高的精度,整个定位过程中,节点间无需额外的通信开销,具有广泛的实用性。
[Abstract]:This paper presents a method of communication and ranging using LFM spread spectrum technology, which can be applied to ranging between wireless sensor network nodes in complex indoor communication environment. On the basis of trilateral location, a four-sided location algorithm is proposed, which breaks through the limitation of trilateral location. In order to further improve the accuracy, the method of centroid and weighted centroid is adopted. The experimental results show that the weighted centroid algorithm has a high accuracy, and it has a wide range of practicability in the whole localization process without additional communication overhead.
