| 摘 要： | 稀布阵列天线具有简化阵列结构、降低系统成本的优点,基于数字波束形成的稀布阵列天线技术获得了广泛地关注。基于作者所提出的多分辨率复合阵列天线技术(MRCA),该文设计了一个多分辨率复合数字阵列天线,并应用该阵列天线来进行单目标和双目标检测实验。仿真和实验结果均表明:与传统的均匀直线阵列天线相比,在相同的阵列天线单元数目的情况下,多分辨率复合数字阵列天线可以得到更窄的主波瓣和更低的副瓣,增强了阵列天线系统的方向性,提高了角度分辨率。

| Abstract: | Because a sparse array has the advantages of a simplified structure and reduced cost in a radar system, radar technology based on the sparse array has gained widespread attention. To take advantage of the sparse array, in this paper, we designed a Multi-Resolution Composite digital Array antenna (MRCA), and then used it in single-target and multi-target detection experiments. Using the same number of array elements, our experimental results demonstrate that the MRCA can obtain a narrower main lobe and a lower side lobe, enhances the direction of the array antenna, and improves the angular resolution compared with the uniform linear array. |
