摘要

本文提出了一种利用一组均匀圆形阵列定位传感器网络中目标三维位置的方法，并给出了理论框架。仿真结果验证了该方法的有效性，并说明了单元模式对到达方向(DoA)估计和定位精度的影响。为了提高方法的鲁棒性，提出了加权最小二乘法(WLSM)。

DoA based positioning employing uniform circular arrays

In this paper, a methodology of employing a set of uniform circular arrays to localize the 3D position of a target in sensor networks is presented and the theoretical framework is given. Simulation results demonstrate the validity of the method and illustrate the effect of the element pattern on the accuracy of direction of arrival (DoA) estimation and positioning. A weighted least squares method (WLSM) is proposed as a means to increase the robustness of the method.
