摘要
本文论述了腔式稳频的改进方法.用腔体检波器输出信号面积的变化表示磁控管振荡频率对腔体谐振频率的偏离比用输出信号幅度变化来表示更合适.将检波器输出信号对时间积分求得面积,经模数转换后输入单片机,由单片机处理后输出数据控制伺服系统,结果使磁控管振荡频率的变化在±20千赫内.
An improved method of frequency stabilization with the resonance cavity was described in the paper. The change of signal area was more suitable than the change of signal amplitude to show the deviation of the oscillation frequency of the magntron from the resonance frequency of the cavity. We could integrate the output of the detector to find the signal area which was converted into data by an ADC and be transferred into the single chip processor and processed. The output of the microprocessor could control the servo to tune the magnetron. As a result, the change of oscillation frequency of the magnetron would be controlled with in ±20KHz.
