Abstract EN
Beamforming algorithm is widely used in many signal processing fields.
At present, the typical beamforming algorithm is MVDR (Minimum Variance Distortionless Response).
However, the performance of MVDR algorithm relies on the accurate covariance matrix.
The MVDR algorithm declines dramatically with the inaccurate covariance matrix.
To solve the problem, studying the beamforming array signal model and beamforming MVDR algorithm, we improve MVDR algorithm based on estimated diagonal loading for beamforming.
MVDR optimization model based on diagonal loading compensation is established and the interval of the diagonal loading compensation value is deduced on the basis of the matrix theory.
The optimal diagonal loading value in the interval is also determined through the experimental method.
The experimental results show that the algorithm compared with existing algorithms is practical and effective.
