摘 要：正In this paper,we present another novel source number estimator without the complete eigendecomposition,it is based on the Lanczos process and Sturm algorithm and Finally,for the case of a Uniform Circular Array of six isotropic sensors spaced a half wavelength apart with additive and uncorrelated white noise,we provide a simulated data example to evaluate the proposed estimator,which is proved to be very available.
