摘要

基于三角测量的辐射源定位是频谱管理中常见的一项任务，通常通过安装在固定或移动监测站内的相关干涉仪估计到达角来实现。讨论了AoA估计技术，并提出了一种特定于调制的算法。仿真结果表明，对于一组特定的调制类型，即非圆调制类型，AoA估计的精度和定位精度都得到了提高。

Modulation-Specific Angle-of-Arrival Estimation Algorithm for Correlative Interferometry

Emitter localization via triangulation is a common task for spectrum management, and it is typically realized by angle-of-arrival (AoA) estimation with correlative interferometers installed within fixed or mobile monitoring stations. The AoA estimation technique is addressed and a modulation-specific algorithm is proposed. Simulation results show that, for a specific set of modulation types, namely the ones which are noncircular, both the accuracy of AoA estimation and that of localization are improved.
