| 摘 要： | 数字波束形成（DBF,Digital Beam Forming）是现代阵列天线系统的关键技术,然而传统的近场天线测量系统与DBF天线的数字接口并不兼容。本文在论述数字波束形成原理的基础上介绍了一种DBF天线近场测量系统。通过对一维DBF天线的近场测量模拟,由近场平面波综合技术得到远场方向图。所得结果与DBF阵列天线远场方向图相比较,可以看出两种方法得到的远场方向图具有良好的一致性。该方法避免了大量探头的使用,克服了探头间的耦合问题。

| Abstract: | Digital beam forming is the key technique of modern array antennas,but the traditional antenna near-field test system is not compatible with digital connector of DBF antennas.This paper presents a DBF antennas near-field measurement system based on the principle of digital beam forming.We used one-dimensional DBF antennas near-field measurements simulation to obtain far-field patterns by the near-field plane wave integrated technology.Compared with DBF array antennas far-field patterns,they have good consis... |
