当PFD在锁定模式中不生成脉冲时，电荷泵不提供电荷给环路滤波器。
When the PFD does not generate pulses in lock mode, the charge pump does not provide charge to the loop filter.
在正常(非校准)操作下，雷达发射器生成脉冲压缩波形，并通过天线发射它。
Under normal (non-calibration) operation the radar transmitter generates a pulse compression waveform and transmits it via the antenna.
