| Abstract: | The possibility of computing the velocity of solar wind by means of co-spectrumtechnique at two frequency 232 WHz and 327MHz is discussed in thes paper. Whenthe effect of integrahon is considered at the elongations 17°-50° with some possiblevelocity distribution, the derived results from co-spectrm tochnique indicate adeviation less than 15% from the velocity of solar wind. |

| Keywords: | Interplanetary scintillation Nomalized co-spectrum Solar wind speed |
