Choice of optimum polarization bases for different radar applications with limited system capabilities

The main polarization bases are compared from the viewpoint of benefits and drawbacks for different radar applications, with regard to the motion of the objects relative to the radar platform during observation and with electronically steered array antennas implemented in multifunction systems with limited polarimetric capabilities and channel deficiencies. Starting from basic scattering models corresponding to the variety of expected types of targets and clutter with mainly horizontal oriented parts the characteristics of the bases are compared with the aim of power maximization with one channel operation and with simple methods of clutter suppression and classification with two channel operation. The advantages of the diagonal polarization basis under distinct assumptions are explained
