摘　　要：为保证较好的可维护性、测试性和可重构性,通常利用多通道T/R组件搭建天线阵面,但是多通道TR组件导致阵面边缘出现量化效应,分析了不同通道TR组件下的边缘量化效应对天线性能的影响,并进行了仿真,通过对比阵面规模、增益损失、副瓣电平等关键参数,给出了一种可行的TR组件通道数量选择方案。For guaranteeing better maintainability,testability and reconfigurability,antenna array is conventionally established by using multichannel TR components,but multichannel TR components result in quantization effect at the edge of the array.This paper analyzes the influence of edge quantization effectiveness on antenna performance and performs simulation,and by comparing the key parameters such as array size,gain loss,sidelobe level,etc,gives a feasible selection scheme of channel number for TR components.
