摘要
雷达MTI系统的性能与雷达发射机的相位及幅度稳定度直接有关。本文叙述一个平均功率为25kW的全固态发射机调制器的人工线电压精密调节器。它将脉冲与脉冲之间人工线电压的变化从0.1％调节到0.024％。这种能力与雷达发射机MTI改善因子50dB的要求相适应。即使在脉冲重复频率变化±13.5％的变T情况下,该调节器也具有较好的功能。
The performance of MTI system is directly related to the phase and amplitude stability of the radar transmitter. A pricision PFN voltage regulator of solid state transmitter modulator with an average power of 25kW is described. By the regulator the voltage variation on PFN at pulse to pulse could be reduced from 0.1% to 0.024%. It can meet the requirement of MTI radar transmitter improvemcnt factor limits of 50dB. Even though staggered pulse-repetition rate varies at±13.5%, the regulator still exhibits a good performance.
