An Introduction to Direction-of-Arrival Estimation Techniques via Antenna Arrays
Department of Electrical and Computer Engineering
This chapter introduces the fundamentals of direction-of-arrival (DOA) estimation techniques for localization systems. The main goal is the introduction of DOA methods via antenna arrays. In order to better introduce the principles of DOA, the chapter first briefly explains antenna systems and antenna arrays. It describes important parameters of an antenna and antenna arrays and the notion of beamforming (BF). The chapter explains different measures for comparing DOA estimation methods and examples of DOA estimation techniques, and discusses their pros and cons. Moreover, it introduces a new DOA estimation method that improves the performance and complexity for implementation on software-defined radios. Finally, the chapter discusses a DOA estimation method that is suitable for periodic sense transmissions in localization techniques such as wireless local positioning systems (WLPSs).
