摘要
The impedance of a solid state active phased array antenna varing with frequency and beam scanning scanning angle be matched with the solid state active matching network (SSAMN). In order to adjust and measure the radar conveniently and Securely, it is necessary for the impedance of the simulator of the phased array antennas to be optimized.Having selected the PIN dilde controlling circuits and the circuit parameters optimized,the simulator circuit is determined through numerical computation The experiment is given in support of the simulation.
固态有源匹配网络可以对随频率和波束扫描角而变化的固态有源相控阵天线的输入阻抗实施良好的匹配．为了方便、安全地调试有源匹配网络，需要对相控阵天线阻抗模拟器进行优化设计．此文采用ＰＩＮ二极管控制电路，将电路反射系数作为优化变量，用数值计算方法确定最终的电路结构和元器件参数．文中给出了相控阵天线阻抗模拟器的测试结果，其结果与模拟计算吻合较好．
