摘要 为快速诊断调试微波滤波器,缩短调试时间,提出了一种基于矢量拟合与渐进空间映射算法的计算机辅助调试方法.首先采用矢量拟合方法提取出滤波器的等效电路参数,再采用空间映射算法预测调谐螺钉的伸入量,从而实现微波滤波器的快速调试.采用提出的方法分别对四阶交叉耦合和六阶切比雪夫滤波器进行调试,仅通过3次和4次迭代便可以逼近理想响应,从而验证了所提方法的准确性与有效性. In order to fast diagnose microwave filters and save the tuning time, a computer-aided tuning method based on the vector fitting （VF） and the aggressive space mapping （ASM） is presented. In this method, the equivalent circuit parameters of the filter are extracted by using the VF, and the tuning value of tuning screws is predicted through the ASM. Thus, the fast tuning of microwave filters is successfully implemented. The proposed method is then applied to a four-order cross-coupled filter and a six-order Chebyshev filter, with ideal responses being obtained respectively through only three or four iterations, which means that the proposed method is accurate and effective.
