一般来说雷达机总是处在各种干扰的情况下进行工作的,为了有效地对付干扰,就经常要求雷达机能在一定宽度的波段内工作.目前,在厘米波雷达发射机中,绝大多数的振荡器均采用磁控管,因此就产生了关于在一定范围内调谐磁控管振荡频率的问题. 调谐磁控管振荡频率行之有效的方法有两种,即机械的方法和电子的方法.电子调谐法用在连续工作的调频发射机中,它是在磁控管的谐振腔的槽中引进 In general, radar machines are always working under various interference conditions, and in order to effectively deal with interference, radar functions are often required to work within a certain band of wavelengths. At present, in centimeter-wave radar transmitters, Most oscillators use magnetrons, thus creating the problem of tuning the magnetron oscillation frequency over a range of frequencies.There are two ways to tune the magnetron oscillation frequency, mechanical methods and electronics Method.Electronic tuning method used in continuous operation of the FM transmitter, which is introduced in the slot of the magnetron’s resonator
