Abstract :
A single source location method based on a independent doublet array is proposed. It is considered that the source is located at the far-field of each doublet and the near-field of the array. The presented method realises direction of arrival estimation by an ESPRIT-like technique, and the range of the source by array geometry successively. It provides a simple and search-free estimation method for single near-field source location. Simulation results are presented that verify the effectiveness of the method.
