引言本文叙述了在采用线型调制器的雷达发射机中,如果要实现良好的动目标显示性能就必须控制若干潜在的相位误差源。许多有关文献认为相位误差来自高压脉冲电源的纹波、参差脉冲重复频率的时序、时间抖动、脉冲形成网络的波动、灯丝电源、聚焦线圈电源和射频激励信号。本文指出了微波管对各种干扰的典型相位灵敏度并论述了相位误差最小化的方法。 INTRODUCTION This paper describes the control of several potential sources of phase error in radar transmitters that use line mode modulators to achieve good moving target display performance. Many sources consider phase errors from ripple of high-voltage pulsed power supplies, timing of jagged pulse repetition rates, time jitter, fluctuations in pulse-forming networks, filament power, focus coil power, and RF excitation signals. This paper points out the typical phase sensitivity of microwave tubes to various disturbances and discusses the method of minimizing the phase error.
