Abstract

Abstract: The basic theory of radar polarization signal processing is measurement of the target scattering matrix. The current algorithm of measurement of the target scattering matrix is gotten through orthogonal dual polarization channel in time-sharing or simultaneously, which demands orthogonal polarization measurement signals with complex coding. The measuring accuracy is higher. The complexity and the cost of the system are relatively higher. Scattering matrix can also be obtained by making use of the spatial polarization characteristics of the antenna to processing the radar echo without structure reformation of the radar. It only. needs to renewal measurement technology. The comparison and performance analysis between the measurement method existed are given by theoretical analysis and simulation experiment. The superiority of the new method is verified which has broad prospects of research & application, although it has some limitation.

Key words: target scattering matrix, polarization, instantaneous measurement, spatial polarization characteristic
