A Method for Joint Estimating 4-D Parameters of Near-Field Sources
一种联合估计近场源四维参数的方法

A method for joint estimating frequency, elevation, bearing and range of near-field narrowband sources is presented. The method uses eigenvalues together with the corresponding eigenvectors and four-order cumulant to estimate 4-D parameters of sources, which does not need spectral peak searching, and it can be applied to additive Guassian noise environments. The effectiveness is verified by the computer simulations.
