提出了一种新型的数字波束形成（DBF）多波束天线阵。在该天线阵中，通过时间序列相位加权（TSPW），使用单个射频（RF）通道恢复阵列孔径上的幅度和相位分布。然后可以使用该分布通过数字波束形成来产生多波束。一个概念验证原型的八元接收阵列在JC波段已经制造和测试。实测结果证实了该方案的有效性和优越性。
A new type of digital beamforming (DBF) multibeam antenna array is proposed. In this antenna array, the amplitude and phase distributions on the array aperture are recovered using a single radio frequency (RF) channel through time sequence phase weighting (TSPW). The distributions can then be used to produce multibeams by digital beamforming. A proof-of-concept prototype of an eight-element receiving array in JC-band has been fabricated and tested. The measured results confirm the validity and advantages of the proposed scheme.
