“…As the accuracy of the Capon spatial spectrum in [31] deteriorates dramatically when coherent signals exist, a low complexity RAB based on the maximum entropy power spectrum is introduced in [40], but it ignores the jamming SV distortion when dealing with arbitrary mismatches. In [41], a novel desired signal SV optimization approach is proposed by designing a desired signal power estimator with uncertainty set constraints, which is more robust to look observation error and array geometry error. The above-mentioned RAB involves three strategies in reconstructing the IPNCM.…”

“…Since traditional adaptive beamforming approaches have weak immunity against even a small mismatch between the presumed and actual signal steering vectors, many robust adaptive beamforming (RAB) techniques have been developed and substantial progress has been made in this area in recent years (see e.g. [2]- [7] and references therein). The mismatch may result from look direction errors, imperfect array calibration, distorted antenna shape, and other reasons [2].…”

“…The beamformer in [48] utilizes subspace orthogonality to reconstruct the NPICM. In [49], a design of SOI power estimator to formulate the SV optimization problem with an uncertainty set constraint is proposed which is different from the conventional Capon estimator in which the desired signal SV is optimized with the Capon power estimator.…”
