脉冲雷达发射机对调制器输出的高压脉冲幅度的稳定性要求很高,这对稳定发射机脉间频率,提高动目标显示质量关系很大.尤其当雷达为了反盲速,采用可变重复周期工作时更是如此.本文介绍稳定线性脉冲调制器输出脉冲的方法.这种电路又叫de-Q(降Q)电路.
Pulse radar transmitters have high requirements on the stability of the high-voltage pulse amplitude output by the modulator, which is of great importance for stabilizing the inter-pulse frequency of the transmitter and improving the display quality of the moving target. Especially when the radar is used for anti-blindness speed, a variable repetition period This is especially true when working. This article describes how to stabilize the output pulse of a linear pulse modulator. This circuit is also called the de-Q (drop Q) circuit.
