Mixed Incoherent Far-Field and Near-Field Source Localization under Uniform Circular Array

Blog Article

A high-accuracy algorithm is presented for the localization of mixed incoherent near-field and far-field narrow-band sources under uniform circular array (UCA).Herein, considering that it is difficult to classify the mixed sources, we first decouple mixed sources’ angles and ranges by calculating centro-symmetric sensors’ phase differences.Then, as the phase differences including only sources’ angles can be transformed as indefinite equations, each source’s Clothing - Junior Bottoms - Pants azimuth angle and elevation angle are obtained by performing the least squares method.After that, on the basis of the estimated angles of the Vacuum Pet Brush mixed sources, one-dimensional (1-D) multiple signal classification (MUSIC) method and corresponding spatial spectrum are utilized to identify the mixed sources and estimate the ranges of the near-field sources.

Finally, simulation and comparison results verify the superior performance of our proposed algorithm.
