• A robust adaptive beamforming method is proposed to cancel coherent, as well as incoherent, interference using an array of arbitrary geometry. In this method, coherent interferences are suppressed by a transformation of received data with the estimates of their arrival angles and then, to reject incoherent interferences, the array output power is minimized subject to the look direction constraint in the transformed signal-plus-interference (TSI) subspace. This TSI subspace-based beamforming results in robustness to errors in the angle estimations. Its performance is theoretically examined. The theoretic results conform to simulation results. It is straightforward to apply the theoretic results to the performance analysis of subspace-based adaptive beamfomers only for incoherent interference cancellation.
