摘　　要：当循环频率估计存在误差时,循环自适应波束形成算法的性能会显著下降。针对这一不足,本文提出了对循环频率误差稳健的循环自适应波束形成算法。仿真实验表明,当存在循环频率误差时,本文提出的算法性能接近没有循环频率误差时循环自适应波束形成算法的性能。The performance of Cyclic Adaptive Beamforming （CAB） algorithm degrades severely when the estimation of the cycle frequency is not accurate. A robust CAB algorithm is proposed in this paper which overcomes the sensitivity to the Cycle Frequency Error （CFE）. Simulations show that the performance of the proposed method when applied to CFE cases is almost as good as that of the original CAB method for the case without CFE.
