In this paper, a new design of the robust adpti-ve beamformer (RAB) is developed to overcome the increased computation cost of the traditional RABs. This approach introduces a suboptimal of the distance between the actual array steering vector (ASV) and presumed ASV in tandem with the iterative doubly constrained robust capon beamformer using fixed uncertainty level (Fu-IDCRCB). Then, the uncertainty...
In recent years, some iterative robust beamforming (RAB) algorithms using a fixed adaptive uncertainty level (Fu-IRAB) are proposed to overcome the SINR performance deterioration of the conventional RAB methods in the presence of large array steering vector (ASV) errors. However, more iteration steps are consumed before the actual steering vector is reached. This paper introduces a new adaptive beamformer...
