In this study, a new mixed near-field and far-field sources localisation algorithm based on sparse signal recovery is addressed. In this scheme, two special cumulant vectors are constructed successively, the first one is used to obtain the azimuth estimations of all the incoming signals, and the second one is used to distinguish the mixed sources as well as estimate the range related to the near-field...
In this study, the authors propose an efficient third-order cyclic moment-based estimation of signal parameters via rotational invariance techniques algorithm to cope with the mixed far-field and near-field cyclostationary sources localisation problem. The key point is that the auto-pairing parameters of near-field bearing and range is realised by estimating the unique non-singular matrix between...
