A novel method for estimating polarization parameters based on SPC of antenna

This paper presents a new method for estimating signal polarization parameters. In the spatial scanning period, the polarization direction of antenna radiation field changes slowly, and the main polarization and cross polarization component approximately satisfy the interesting phenomenon of multicollinearity. Using this characterization, the received signals are joint processing in both spatial and temporal two-dimensional, a new ridge estimation method of radar echo signal polarization parameters or array incident signals is designed. Theoretical analysis and simulation results show the effectiveness of the method, which can improve the estimating accuracy.
