摘　　要：提出了由相位噪声计算信号谱线宽度的计算公式 ,从而计算出脉冲多普勒雷达频综器输出的激励信号的谱线宽度 。A computation formula for the spectral width of a signal is presented, which is a function of phase noise. The spectral width of an excitation signal in the frequency synthesizer of a pulse Doppler radar is then calculated, and it is found that it is impossible for general instruments to measure the spectral width of a low phase noise signal accurately.
