摘要：

A modified forward-backward averaging algorithm to estimate the covariance matrix in beamspace DBF is proposed. The computation is greatly reduced because the complex number operation is replaced with real number operation with the special structure of symmetrical array. Simulation results show that the proposed algorithm can preserve its interference suppression ability with the reduced computation.
