Signal Estimation under Specific Direction based on Extrapolation Method

Abstract

Abstract. For the problem of space spectrum cannot reserve the original time-domain signal under specific direction after beamforming, a method of primitive signal estimation based on the results of beamforming is proposed. The method proposed is based on the traditional extrapolation, and can be used to estimate the signal of the virtual array sensors. Simulation results of both amplitude and phase show the veracity of the estimated signal.
