摘要
简述了某系统设备中相控阵天线的结构组成、尺寸精度和结构特点。介绍了采用不锈钢挠性连接的结构方式和殷钢材料控制天线形变的方法,这些方法有效地减少并控制了天线因温度变化而产生的形变,保证了天线的发射和监测精度。
This paper discusses the structural constitution, dimensional precision, structure characteristics of Phased Array Antenna for some landing system. We use stainless steel flexible connection and invar material to control shape variation of Phased Array Antenna. This method effectively reduced and controlled the shape change of antenna by temoerature, and the precision of antenna pattern and surveilance is ensured.
