A single port receiver spatial spectrum estimate DF system

Abstract

A new method of DF (direction finding) using spatial spectrum estimation technology is proposed. Based on the covariance matrix obtained by the weight perturbation algorithm, we use a single port receiver for spatial spectrum estimation DF. In principle, the proposed method is adapted for any eigenstructure algorithm. The computer simulation results of the spatial smoothing algorithm show that the proposed DF method is efficient and very feasible for practical applications.
