| Abstract: | The equations for estimating the rain echo power when FM-pulsed radar or FM-CW radar is used are derived. The results show that, with adequate frequency range selected, rain echo power may have a well-linear correlation with the rainfall rate, irrespective of the pattern of drop-size spectrum. Thus, it provides good remote sensing data for rainfall rate measurement. |
