本文回顾了已知的正交场放大管（CFA）噪声性能的实际测量数据，并且讨论了脉冲调制的CFA在脉冲多普勒雷达中的有用特性。
The known actual measured noise characteristic data of CFAs are reviewed, and the usefulness of pulse-modulated CFAs in pulsed Doppler radars are discussed in this paper.
接收机的每个通道都由高频放大器、中频放大、中频采样、数字正交器组成，另外还有DDS信号产生和频率激励源用来形成雷达发射机所需的S波段脉冲调制激励信号。
Each of them is composed of high frequency amplifier, intermediate frequency amplifier and sampling, digital phase uprightness intersector, DDS and the S band signal inspirator for the transmitter.
