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。
Front-surface monitoring is an important self-monitoring method for array antenna array testing and working. Frontier monitoring can detect abnormal channels in the digital array antenna and avoid affecting the performance of frontal planes. Firstly, the principle and classification of the array surface monitoring of the digital array antenna are introduced, and the application scenarios of various monitoring types are analyzed. Then, several common types of channel faults in the surface monitoring are described in detail, and the types of these fault types The method of monitoring and the basis of judgment; finally, combining the actual field test, comparing the result of front face monitoring with that of actual channel, it proves the effectiveness of this front face monitoring method, and verifies the beamforming results before and after the front face monitoring processing The Effect of Front Monitoring Method on Digital Array Antenna.
