Space-polarization Domain Multi-beam Parameter Estimation for Dual Polarized Conformal Array

A space-polarization domain multi-beam parameter estimation algorithm is proposed for the conformal arrays composed of dual polarized antennas. The polarization signal can be broken down into two orthogonal polarization components. The dual polarized conformal array has strong polarization processing ability, which can form a multi-beam covering space-polarization domain. The multi-beam contains angle and polarization information, and each beam only receives signal of a certain angle and polarization state. Therefore, the signals of different angles and polarization states have different response distributions to these beams, and this characteristic can be used for the direction of arrival (DOA) and polarization parameter estimation. In addition, the process between the polarization parameter and the angle estimation does not affect each other and can be estimated simultaneously. Finally, simulation results demonstrate the effectiveness of the proposed algorithm.
