摘要

为了降低传统变换域波束形成器的计算复杂度，本文提出了一种变换域部分自适应波束形成器，该波束形成器在对输入信号进行变换后，利用单元平均恒虚警率(CA-CFAR)处理器，只对变换后的系数对应的权重中预期包含干扰的部分进行自适应。CA-CFAR处理器的虚警率也可以根据输出功率的变化自适应地改变。

Two-dimensional transform-domain partially adaptive beamformer

This paper proposes a transform-domain partially adaptive beamformer to reduce the computational complexity of conventional transform-domain beamformers, After transforming the input signals, the proposed beamformer adapts only those parts of the weights that correspond to the transformed coefficients expected to contain interference by using the cell averaging constant false alarm rate (CA-CFAR) processor. The false alarm rate of the CA-CFAR processor is also changed adaptively according to the variation of output power.
