摘　　要：针对毫米波亚毫米波探测仪对准光学馈电网络的需求,基于GRASP软件设计了一套23~425 GHz 10频段准光学馈电网络。采用平面折返镜实现双层准光学馈电网络设计,有效控制系统结构包络;通过极化栅网和频率选择面(FSS)分离通道,对通道指标进行仿真分析。采用平面近场方法对准光馈电网络辐射性能进行测试,测试结果满足指标要求。Aiming at the requirements of millimeter and sub millimeter wave radiometer for quasi optical feed network,a 23~425 GHz ten channels quasi optical feed network is designed by GRASP software,using flat plane to achieve a double layers quasi optical feed network and reduce the size,using polarization grids and Frequency Selective Surfaces(FSS)to separate different channels.Through simulating the specifications of each channel,the test results are consistent with the simulation results.
