【摘要】 分析有源相控阵天线阵面变形对电性能的影响,对高性能天线的工程研制具有重要的意义。基于阵面辐射单元的位置误差分析,建立了矩形平面相控阵天线阵面变形对电性能影响的结构与电磁耦合模型,并分析了阵面平面度与安装精度对天线电性能的影响。工程设计人员可在电性能变化允许范围内,依据该方法对天线的加工公差提出合理的要求。更多还原

【Abstract】 The analysis of electromagnetic performances of rectangular active phased array antennas with distorted plane errors is important to the engineering development of high-performance antennas. A coupled structural-electromagnetic model of active phased array antenna is developed based on the plane radiating element position errors caused by antenna structural distortion. The application of the model to a planar array antenna demonstrates the degradation of the sidelobe level and gain of antenna with the different distortion grade. The good analysis results can provide a theoretical guidance for the engineer to determine the structural tolerance.更多还原
