摘要
接收波束形成是阵列信号处理中的重要部分。经典Capon波束形成算法虽然可以形成理想波束,但需要精确获知信号的到达方向(DOA)。在实际应用中,由于模型失配可能会造成DOA失配。因此提出了一种非退化椭圆约束条件下的稳健波束形成算法,允许在出现DOA失配情况下依然可以有效地接收信号,同时利用仿真验证了算法的可靠性。
Receiving beam forming is the important part of array signal processing. Although tradi- tional Capon beam forming algorithm can form ideal beams, but the signal direction of arrival (DOA) needs to be known accurately. Because the model miss-match may result in DOA miss- match in the actual application,this paper puts forward a robust beam forming algorithm in the re- striction condition of non-degradation ellipse, which permits the signals be effectively received in the situation of DOA miss-match,and verifies the reliability of the algorithm through simulation.
