Abstract

This paper discusses the architecture of an adaptive transmitting antenna array that allows highly flexible beamsteering. Antenna arrays are used in many digital signal processing applications due to their ability to locate signal sources. The Direction of Arrival (DOA) estimation is a key task of array signal processing, with the Taguchi method and Multiple Signal Classification (MUSIC). Although various algorithms have been developed for DOA estimation, their high complexity prevents their use in real-time applications. In this paper, we design and develop an implementation using Field Programmable Gate Array (FPGA Artix-7), which is the most widely used ARM processor in embedded systems. The antenna array is digitally controlled with the phases synthesized by the Taguchi method.

采用FPGA-ARM Cortex-M处理器控制相控阵天线
本文讨论了一种允许高度灵活波束导向的自适应发射天线阵列的结构。由于具有定位信号源的能力,天线阵列被用于许多数字信号处理应用中。DOA估计是阵列信号处理中的一个关键问题,有田口法和多信号分类。虽然已经开发了各种用于DOA估计的算法,但它们的高复杂性阻碍了它们在实时应用中的应用。本文采用嵌入式系统中应用最广泛的ARM处理器——现场可编程门阵列(FPGA Artix-7)设计并开发了一个实现。天线阵列采用田口法合成相位进行数字控制。
