three-state control signal

There is a serious requirement for phase consistency of T/ R model from active phase control array radar. The test for pulse signal phase is comparatively complicated. Three phase test methods for the microwave pulse power amplifier are presented in this paper.

有源相控阵雷达对T/R组件相位一致性有严格的要求，脉冲信号相位的测试比较复杂，本文提出了三种微波脉冲功率放大器相位的测试方法。
