摘　　要：矢量天线调谐器是近年发展的新型天线调谐器。从矢量天线调谐器的硬件结构入手,分析使用阻抗变换器将目的阻抗变换到200Ω的矢量天调硬件结构对调谐算法的影响及其优缺点,并介绍了200Ω的阻抗矢量天调的调谐方法,分析工程应用中的各个调谐步骤的常见误差特性和对调谐结果的影响,提出了各调谐步骤对应的修正方法,解决了矢量天调配置匹配网络后的误差修正。最后,对10 m和3 m短波鞭状天线进行对比测试,验证了算法的有效性。The vector antenna tuner is a new type of antenna tuner developed in recent years.Starting from the hardware structure of the vector antenna tuner,the influence of the hardware structure of the vector antenna tuner,which uses impedance converter to transform the target impedance to 200Ω,on the tuning algorithm and its advantages and disadvantages are analyzed.The tuning method of 200Ωimpedance vector antenna tuner is introduced,and the common error characteristics of each tuning step in engineering applications and the influence on the tuning results are analyzed.A correction method corresponding to each tuning step is proposed to solve the error correction after the vector antenna tuning configuration matches the network.Finally,a comparison test of the 10-meter and 3-meter short-wave whip antennas is performed to verify the effectiveness of the algorithm.
