摘　　要：发射信号频谱质量的好坏与雷达动目标探测性能高低密切相关。文中分析了脉冲调制波形前后沿抖动、电网谐波、速调管工作状态等方面因素,对发射机射频信号频谱质量产生的影响。同时,以一套速调管发射机为实验系统,进行实验分析和验证。以实验数据的形式,分别指出以上各种因素对发射系统射频功率频谱质量影响程度。对速调管发射机的工程应用,具有一定的指导意义。The quality of frequency spectrum of transmitted signal could affect the quality of moving target indicator detection of ra- dar. The factors, such as modulation pulse, harmonic component of electric network and working state of the klystron, are ana- lyzed, which have the influence on transmitter frequency spectrum quality. A series of experiments are processed on a experimental model with klystron. Then, a mass of experiment data is offered to prove the effects on the transmitter frequency spectrum quality. It is of benefit to the engineering application of the transmitter with klystron.
