| 摘要: |
| 在脉冲雷达发射机中由于电源的谐波影响，会对最终的发射信号频谱产生影响，进而影响雷达动目标探测性能。本文就实际工程中遇到的信号频谱恶化问题提出了解决的方案，达到改善发射信号频谱的目的，并用实际的测试结果进行了验证。 |

| Abstract: |
| The mainsupply harmonic wave in pulse-radar transmitter will affect the quality of frequency spectrum of transmitted signals, and even affect the quality of Moving Target Indicator(MTI) detection of radar. This paper proposes a scheme to improve the quality of frequency spectrum of transmitted signals, and also validates the method by the actual test result. |
