Advances in DOA Estimation and Source Localization
Description
Direction of Arrival (DOA) estimation is a hot research topic in various areas including radar and communications. DOA estimation is often implemented using either antenna arrays or multiple antennas working cooperatively. As radar and communications services proliferate, the need for novel, fast, and accurate DOA estimation techniques has become more pertinent. In automotive radar, for instance, antenna arrays are being deployed to enable applications such as emergency braking. In communications, the quality of wireless services can be greatly enhanced if the user information is known. In navigation, DOA estimation and interference localization permit interferers to be disabled, which is essential in safety critical applications such as air travel.
High-resolution methods (such as subspace based techniques) can achieve very good resolution and accuracy but at the expense of high computational cost. They also cannot be applied in the single snapshot case unless spatial smoothing is employed, which compromises both the resolution and accuracy. Discrete Fourier Transform (DFT) methods, on the other hand, are computationally much simpler and suitable for the single snapshot case but have traditionally only been able to deal with one single source at a time. In the multiple sources case, these methods suffer from low resolution and degradation due to leakage effects.
The aim of this special issue is to publish original research as well as review articles on recent advances in technologies and techniques for enhanced DOA estimation and its applications in radar, sonar, wireless communications, and other fields.
