Prospective investigations with DFVLR radar of possible relevance in the assessment of radio interference due to scattering from precipitations

A coherent polarimetric weather radar is described. The radar technique for remotely sensing meteorological precipitations is generalized and applied to hydrometeor volumes capable of producing significant electromagnetic scattering. The impact of the radar on the characterization of the distribution and the thermodynamic phase of the hydrometeors is discussed. The polarimetric capabilities of the radar in characterizing the propagation medium and the removal of propagation effects present in the radar echoes are outlined. A T-matrix method for calculating scattering properties of double-layer hydrometeors is presented.
