数字阵列天线的阵面监测方法研究

阵面监测是数字阵列天线在阵面测试和工作过程中的重要自检监测手段，阵面监测可检测出数字阵列天线中存在异常的通道，避免这些通道对阵面性能造成影响。文中首先介绍了数字阵列天线的阵面监测原理及分类，并对各种监测类型的应用场景作了分析；然后，详细描述了阵面监测中几种常见的通道故障类型、以及这些故障类型的监测方法和判断依据；最后，结合实际阵面测试，将阵面监测结果与实际通道性能进行比较，证明了该阵面监测方法的有效性，对比阵面监测处理前后的波束形成结果，验证了阵面监测方法对数字阵列天线的作用。

A Study on Array Monitor Methods of Digital Array Antenna

Array monitor is an important self-monitor method of digital array antenna while antenna testing or radar normal working. Array monitor can find the abnormal channels in digital array antenna, and avoid the effects to antenna. Firstly, the principles and assortments of digital array antenna monitor are introduced, and the application scenarios of each monitor method are analysed. Secondly, several common channel abnormal types are described and the monitor methods and determinants of these types detailedly are introduced. Finally, are described the array monitor results with the real channel properties in actual array test are compared. The result verifies the availabilities of these array monitor methods. The beam forming result comparison of before and after array monitor provides the effort of monitor methods to digital array antenna.
