摘要:Abstract(#br)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 pat...

摘要:Abstract(#br)Comparison of meteorological tower measurements with a high resolution CW-FM radar indicates that the device is applicable to studies of structure of temperature inversions, stable and unstable waves upon such inversions, thermal plumes and convective processes withi...

摘要:An out-of-band (OoB) emission modelling of high-power pulse linear frequency modulation (PLFM) radar is proposed in this study. Aiming at the frequency-domain characteristic of the OoB emission, the analytical expression of the frequency-domain model by simplifying the Fresnel in...
