Abstract A new theoretical model for target scattering characteristic measurement based on ordinary mono-pulse radar system is proposed in this paper. The complexity of polarization structure in mono-pulse antenna is proved firstly. It is verified to be sensitivity to the polarization of target returns. Based on the polarization characteristics of sum-and-difference channel in mono-pulse radar, the PSM of target can be measured by signal processing of received signal in only one pulse interval which can be implemented greatly reduce the development complexity and production cost of fully polarimetric radar. By processing the electromagnetism computation data and simulation experiments, the validity of research work is demonstrated. All above have significant illumining and directing meaning for exploiting polarimetric measurements capability of current radar equipments and enhancing their information acquisition and processing capacity.
