| 摘 要： | 当快拍数较少和存在系统误差时，自适应波束形成性能急剧下降，特别是当输入信噪比较大时，会出现严重的信号相消现象．文中利用时域信息提出一种新的自适应波束形成方法，理论分析表明，该方法为目标多普勒频率已知条件下最大似然估计结果．该方法能有效地克服信号相消现象，并且具有良好的波束保形能力和快速收敛特点，计算机仿真结果验证了这些优点

| Abstract: | A small number of samples and system errors can seriously degrade performance in adaptive arrays, particularly when the input signal to noise ratio (SNR) is large. In this paper, a new adaptive beamforming method based on using signal Doppler information is proposed. It has the advantages of eliminating the problem of signal cancellation, a good beam pattern with the properties of low sidelobe level and fast convergence, which are confirmed by computer simulations. |
