OFDM waveforms for a fully polarimetric weather radar

Retrieval of cloud parameters in weather radar benefits from polarimetric measurements. Most polarimetric radars measure the full back scatter matrix (BSM) using a few alternating polarized sounding signals. Using specially encoded orthogonal OFDM signals however, the BSM can be measured in a single simultaneous transmission of two orthogonally polarized signals. Based on a set of parameters for weather radar, the properties of such a signal are explored and its merit as a useful capability is shown.
