摘要

有源相控阵天线(Active Phased Array Antenna

APAA)阵面安装产生随机误差

振动冲击、热功耗等引起阵面变形

二者产生的阵面结构变形误差会导致天线电性能的下降

已成为实现高性能APAA的难点之一.将阵面变形误差作为附加的相位因子引入到天线方向图函数中

建立了平面矩形APAA阵面变形误差与电性能之间的结构-电磁耦合模型

并仿真分析了天线阵元个数变化时

阵面变形误差对天线电性能的影响规律.

Abstract

The electromagnetic performance of active phased array antenna (APAA) is obviously degraded because of plane distortion errors which include random errors generated in antenna plane assembling and structural distortion resulting from vibration

thermal power consumption

etc.It has become one of the difficulties to develop high-performance active phased array antennas.By introducing the plane distortion errors into the antenna pattern function as an additional phase factor

the coupled structural-electromagnetic model between the plane distortion errors and the performance of the planar rectangular APAA is established.The influence of the electromagnetic performances of antenna with the plane distortion errors is analyzed with the valueful results.
