| 摘 要： | 提出了一种新的传感器节点角度测量方法，即在信标节点发出变频干涉波，通过检测干涉场各点处合成波强度的变化频率来确定未知节点的角度的测量方法。经实验证明，该方法简单易用，对节点要求低，精确度高，是一种适用于无线传感器网络的新的角度测量法。

| Abstract: | This paper proposes a new method to locate the nodes that use the interference of waves.Beacon node sends interferenced waves and then increases the frequence,the amplitude and intensity of the unknown nodes around the beacon will change.The change frequences of intensity of nodes in different directions are different.Through making use of the variety frequences to gain the angles.This new method is easier to use for the small nodes and is suitable for the energy efficient WSN. |

| Keywords: | angle measurement interference waves intensity change frequence Wireless Sensor Network（WSN） |
