Abstract

Abstract

Near-field source localization plays an important role in the radar, sonar and communications. The near-field source localization methods and the resolving ambiguity methods via uniform circular array are systematically introduced in this paper. On this basis, the fast and accurate algorithms for three-dimensional position parameter (azimuth angle, elevation angle and range) estimation of near-field Linear Frequency Modulated (LFM) signal are further introduced from time domain, frequency domain, and fractional Fourier domain. Finally, the following research ideas are proposed from the aspects of coherent source and mixed source localization.
- Uniform circular array,
- Near-field source localization,
- Resolving ambiguity,
- Linear Frequency Modulated (LFM) signal
