Um método robusto de formação de feixe adaptativo é proposto para cancelar interferências coerentes e incoerentes usando uma matriz de geometria arbitrária. Neste método, as interferências coerentes são suprimidas por uma transformação dos dados recebidos com as estimativas de seus ângulos de chegada e então, para rejeitar interferências incoerentes, a potência de saída da matriz é minimizada, sujeita à restrição de direção de olhar no sinal mais interferência transformado ( TSI) subespaço. Esta formação de feixe baseada em subespaço TSI resulta em robustez a erros nas estimativas de ângulo. Seu desempenho é examinado teoricamente. Os resultados teóricos estão em conformidade com os resultados da simulação. É simples aplicar os resultados teóricos à análise de desempenho de beamfomers adaptativos baseados em subespaço apenas para cancelamento de interferência incoerente.

Abstract: 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.
