A new method based on third-order cyclic moment is presented for the directions-of-arrival (DOA's) and range estimations of near-field sources. By exploiting the cyclostationarity and space-time information of the signals, the parameters are directly given by the eigendecomposition of certain constructed DOA-matrix. Compared with several existing approaches, the loss of array aperture is voided since...
Parameter estimation for nonstationary chirp (LFM) signal is a noticeable signal processing problem that shows up in many applications. A special time-varying higher order moment approach is proposed here to realize multicomponent chirp signals parameter estimation. Though chirp signal is nonstationary, its special time-varying fourth order moment in this paper is a function independent of time. Namely...
