| Abstract: | 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. |
