Abstract

In this paper, we present a system specialized for measuring the direction-of-arrival (DoA) of electromagnetic waves with noticeable simplicity. Unlike common methods, which are based heavily on complex computation and signal processing, our proposed system is considerably simpler, both in terms of design and operating theory. Our design consists of two directional antennas for collecting incident waves, a system of Wilkinson power combiners and dividers in which the waves collected by the antennas interfere, a result-processing block consisting of power amplifiers, rectifiers, and a microcontroller unit that respectively converts the interferometric radio-frequency (RF) signal into direct-current (DC) signal, measures its corresponding power before calculating the incident angle solely based on a simple trigonometric equation. The system yields a high accuracy of less than 7.5o with the incident angle ranging from −60o to 60o.

一种简单的基于干扰和功率的现代通信到达方向测量系统

在本文中，我们提出了一个专门用于测量电磁波到达方向(DoA)的系统，该系统非常简单。与基于复杂计算和信号处理的常见方法不同，我们提出的系统在设计和操作理论方面都要简单得多。我们的设计包括两个收集入射波的定向天线，一个由威尔金森功率合成器和分频器组成的系统，其中天线收集的波会进行干扰，一个由功率放大器、整流器和一个微控制器组成的结果处理模块，分别将干涉射频(RF)信号转换为直流(DC)信号。测量其对应的功率，然后计算入射角，完全基于一个简单的三角方程。该系统在入射角范围为- 60到600度的情况下产生小于7.5度的高精度。

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
