数字化相控阵天线测试方法及测试系统设计

伴随着雷达技术的飞速发展,数字化相控阵天线开始广泛运用于各种相控阵雷达当中。由于数字化相控阵天线的工作原理与传统模拟相控阵天线差异极大,测试方法也发生了根本性的改变,原有的基于普通微波仪表的天线测试系统无法再对数字化相控阵天线进行测试,必须设计新型的数字化相控阵天线测试系统。本文首先介绍了数字化相控阵天线自身的工作原理和测试方法,随后提出了新型数字化相控阵天线测试系统的具体软硬件设计方案,实际应用表明数字化相控阵天线测试系统可以满足各种数字化相控阵天线的测试要求。

Test method and test system design of digital phased array antenna

With the rapid development of the radar technology, digital phased array antennas have been widely used in various kinds of phased array radar. Due to the great difference of the principle between digital phased array antenna and conventional analog phased array antenna as well as the fundamental change of test method, original antenna test system based on common microwave instrument can no longer test digital phased array antenna and a new type of digital phased array antenna test system design is needed. This paper firstly introduces the working principle and test method of digital phased array antenna, and then proposes the concrete hardware and software design of new digital phased array antenna test system. The practical application shows that the digital phased array antenna test system can meet a variety of test requirements of digital array antenna.
