和波束和差波束是单脉冲雷达系统中常用的两种波束方向图，用于目标的探测和跟踪。本文提出了一种基于二进制可编程亚曲面(BPM)的和差波束合成方法。此外，可以通过对BPM的数字编码方案进行重新编程来控制和波束和差波束。在Ka波段设计并测试了BPM的样机。仿真和实验都验证了所提出的波束整形和波束控制功能。
Sum and difference beams are two kinds of field patterns, which have been commonly used in monopulse radar systems for detecting and tracking targets. This letter proposes to synthesize sum and difference beams based on a binary programmable metasurface (BPM). Moreover, the sum and difference beams can be steered by reprogramming digital coding schemes of the BPM. A prototype of the BPM is designed and tested at the Ka-band. Both simulations and experiments validate the presented functions of beam shaping and beam steering.
