Capon beamforming has better resolution and interference rejection capability. However, its performance will seriously degrade due to noise, array steering vector error, and other factors. In this paper, a robust Capon beamforming applied to a planar array is described. It is shown that the proposed method is the natural extension of the original Vector Optimization Robust Beamforming algorithm to the case of a planar array, and can be reformulated as a convex second-order cone program and solved by SEDUMI. Computer simulation has shown that the proposed method has better performance than other conventional methods, such as narrower main lobe and lower side lobe.

A robust Capon adaptive beamforming imaging method was proposed for stepped-frequency through-the-wall radar. According to the ideal of robust Capon beamforming (RCB) under the steering vector uncertainty set, Capon optimal weight vector in frequcency domain is obtained by accurately estimating Compensation function vector. Then signal energy is estimated by freqency weighting, and coherence factor (CF) weighting is applied to suppress sidelobe level. Therefore, this method not only achieves higher resolution and much better interference suppression capabilities, but also improves imaging contrast.

Existing robust Capon beamformers achieve robustness against steering vector errors at a high cost in terms of computational complexity. Computationally efficient robust Capon beamforming approach based on the reduced-rank technique is proposed in this paper. The proposed method projects the received data snapshots onto a lower dimensional subspace consisting of the matched filters of the multistage Wiener filter (MSWF). The subsequent adaptive beamforming will then be performed within this subspace. The combination of the benefit of the robust adaptive beamforming and the reduced-rank technique improves the performance on combating steering vector errors and lowering the computational complexity.

Анотація:

Recently, adaptive array beamforming has been applied to medical ultrasound imaging and achieved promising performance improvement. However, the current robust Capon beamformer with spatial smoothing (RCB-SS) is implemented in the time domain, which does not fully utilise the large bandwidth of ultrasound signals and spatial smoothing reduces the effective aperture. In this dissertation, we propose a robust Capon beamformer with frequency smoothing (RCB-FS) and compare its performance with RCB-SS. To further reduce the speckle noise and utilise the large bandwidth of the signal, we combine RCB-FS and frequency com- pounding (FC) and propose a robust Capon beamformer with frequency smoothing combined with frequency compounding (RCB-FS-FC). The proposed RCB-FS method shows a narrower mainlobe width, lower sidelobes, better reconstruction at higher depths and less speckle than RCB-SS. FC is an e ective method to improve the contrast resolution and suppress speckle noise by combining sub-band images, at the expense of resolution. Compared to standard FC, the proposed RCB-FS-FC method has a better contrast resolution and speckle reduction and a significant improvement in resolution. RCB-FS offers a promising approach to find the optimal weights for the transducers in forming the sub-band images needed for frequency compounding.
