Preconditioned methods for Space-Time Adaptive Processing

Abstract

This paper introduces the preconditioned methods for Space-Time Adaptive Processing (STAP). Using the Block-Toeplitz-Toeplitz-Block (BTTB) structure of the clutter-plus-noise covariance matrix, a Block-Circulant-Circulant-Block (BCCB) preconditioner is constructed. Based on the preconditioner, a Preconditioned Multistage Wiener Filter (PMWF) which can be implemented by the Preconditioned Conjugate Gradient (PCG) method is proposed. Simulation results show that the PMWF has faster convergence rate and lower processing rank compared with the MWF.
