Study of MVDR Adaptive Beam High Resolution Bearing Estimation Algorithms Based on SMI

Abstract:

This dissertation systematically studies beam space high resolution bearing estimation algorithms. The solution to target resolving and bearing estimation is proposed to remove the contribution from interferes outside the beam coverage area. MVDR adaptive beam based on sample covariance matrix inversion (SMI) is demonstrated for the condition under which strong interferes and signals are weakly correlated. For the situation that strong interferes and signals are strongly correlated, MVDR beam forming algorithm based on virtual interferes is proposed to suppress strong interferes. Simulation results indicate that the beam space MUSIC algorithm based on MVDR is an effective way to resolve multiple targets in small angle domain.
