摘　　要：传统微波阻抗匹配技术很难对动态负载做到实时、快速、稳定的匹配。针对这一问题,本文构建了一个能够为动态负载提供实时快速匹配的智能阻抗调配系统。该系统将三探针检测技术与三销钉调配器进行集成,利用三探针检测器实时检测动态负载反射系数的变化,同时将检测到的反射系数传输到微处理器,由微处理器进行处理,控制步进电机调节三销钉调配器,将反射系数稳定在工程理想值范围内,从而实现微波系统动态负载的阻抗匹配。Traditional microwave impedance matching technology is unable to achieve real-time,fast and stable matching for dynamic load.An intelligent impedance matching system is set up to solve this problem.The system integrates three-probe detection technology with three-stub tuner.The reflection coefficient change of dynamic load is detected by the three-probe detector and then the signal is transmitted to a microprocessor.The microprocessor processes the signal and consequently adjusts the three-stub tuner through a stepper motor to stabilize the reflection coefficient in engineering desirable range,so as to realize impedance matching of dynamic load in microwave system.
