对短波发射天线DBF系统进行有效的监测具有重要的意义。本文从满足系统实时性与精确性兼顾的要求出发,分别介绍了内外监测法,内监测具有实时性好的特点,外监测可全通道测试。因此建议提高精度可采用环路校准法,从而将尽可能消除测试系统的误差,采用中场测试加数据拟合消除空间干扰的影响。
It is significant to monitor the shortwave transmitting antenna DBF system effectively. This paper, starting from meeting the requirement of real-time and accuracy of the system, introduces the internal and external monitoring methods respectively. The internal monitoring has the characteristics of good real-time, and the external monitoring can test the entire channel. Therefore, it is recommended to improve the accuracy of the loop calibration method, which will try to eliminate the error of the test system, the use of midfield test plus data fitting to eliminate the impact of space interference.
