Research on Conversion Matrix and Optimal Polarization Angle of Radar Oblique Polarization Detection

When radar detects targets, different polarization modes and parameters have different effects on target detection. In order to study the influence of the change of polarization angle on RCS in oblique polarization detection, a transformation matrix from horizontal polarization to oblique polarization at any angle is proposed. The relationship between horizontal/vertical polarization scattering matrix and oblique polarization scattering matrix can be derived through this matrix, and the oblique polarization RCS is expressed as a function of oblique polarization angle. The maximum value of the function is solved and the optimal detection polarization angle is determined.
