微波大功率输出及其控制技术研究

针对传统的微波功率输出以单片机控制为主的控制技术，系统稳定性差、精度低且输出功率小的问题．文中提出了一种以DSP为控制部分的多磁控管微波输出系统。采用DSP、可控硅技术以及微波理论，通过控制磁控管阳极电流来控制各磁控管微波功率的变化，并采用多路耦合技术，提高了整个系统的微波输出功率．完成了其阳极电流、电压等性能指标的测试，使微波输出功率的耦合度达到95％，系统运行稳定，满足了实际测试要求．

Technology for High Power Microwave Output and Its Control

The traditional technology for controlling microwave output power with SCM control system is of poor stability, low precision and small output power. This paper presents a DSIP microwave output system. With DSP technique, controllable silicon technology and microwave tlheory adopted, the magnetron microwave power change is controlled by controlling the magnetron anode current, and uses the multiple coupling technology to increase microwave power output. The anode current, voltage and other performance indicators are tested. The microwave output power coupling is increased to 95 %and the system operates well,meeting the testing requirements.
