机载电子战系统有源相控阵天线的完整参数检测方法步骤复杂且消耗时间较长,文中基于有源相控阵天线波束捷变特性设计出新的天线检测方法,可实现有源相控阵天线检测过程自动化,从而大幅提高天线全波位、多频点方向图参数测量速度,并使用改进的灰色关联度数据分析算法(GRA),对测量所得的参数集进行快速计算与故障原因分析。为机载电子战系统有源相控阵天线的研制、开发、检测提供了技术支持。

The intact-parameter detecting method of the airborne EW system's active phased array antenna comprises complicated steps while consumes considerable time. The novel antenna-detecting method is proposed in this paper, which can realize the auto- matic detection of the active phased array antenna and largely accelerate the parameter measurement of the antenna pattern, is designed based on the beam-agility characteristics of the active phased array antenna. An improved grey relevancy data鄄analyzing algorithm (GRA) is applied to perform the swift calculating and fault-cause analysis to the measured parameter sets. Technical supports to the studying, developing and detecting of the airborne EW system's active phased array antenna is provided.
