中文摘要：

为了解决对未知干扰源定位的问题，采用基于检测概率和波达角估计的单接收机定位方法，只需一个参考节点就可以确定干扰源的位置。该方法采用能量检测作为接收机的感知模型，利用接收机的感知结果估计距离参数；使用天线阵列的测量数据，采用多重信号分类算法估计角度参数，从而得到目标的坐标。仿真实验证实了该方法精度较高，能够有效估计干扰源的位置。

英文摘要：

This paper studies the localization algorithm for a single-receiver based on the detection probability and DOA estimation the problem of locating the interference source by using one reference node. The energy detection is used as a sensing model to acquire the distance; and the MUSIC is used to acquire DOA, and then the coordinate of the target can be obtained. The simulation results show that the proposed algorithm can effectively estimate the position of the interference source.
