Abstract
Highlights •A definite joint extension model based on bidirectional linear prediction (LP) and inverse beamforming (IBF) is proposed for realizing a larger virtual aperture significantly.•A novel MVDR beamformer based on the larger virtual aperture array is designed to get higher azimuth resolution, more DOFs, and lower sidelobe inhibition.•A spectrum selection is conducted to reduce the computation time through the shorter data length in the frequency domain.
