Characterizing the performance of spaceborne weather radars for observations of precipitation and clouds
Abstract: This thesis explores a new antenna configuration for accurately obtaining Doppler measurements from a spaceborne weather radar. Spaceborne weather radars have the potential to observe the dynamic process of the atmosphere at a global scale. Unlike ground and airborne radars, spaceborne radars have a unique challenge due to high orbital velocities of the platforms, which result in a decorrelation of successive pulses, adversely affecting the ability to accurately measure the vertical Doppler velocity of clouds and precipitation. A Displaced phase center antenna (DPCA) configuration has been proposed to mitigate the effects that high platform velocities have on single antenna system on a spaceborne weather radar. This thesis evaluates the performance for Doppler velocity estimation from DPCA.
