Polarization selectivity and Optimization of thinned array for Millimeter Wave radar seeker with conformal phased array
A novel criterion for thinned array optimization based on optimal polarization (minimization of the cross-polarization level) is proposed to suppress the cross-polarization level and solve the problem of grating lobes arisen from thinned array in Millimeter wave conical phased array. The mathematical model based on the radiation pattern of the radar seeker polarization is developed firstly. Then the optimal polarization mode is chosen by comparing the cross-polarization level of circular polarization with that of linear polarization, and then two groups of basic parameters are determined. Finally, the modified particle swarm optimization algorithm is applied to optimize the configurations of the elements, while suppressing the grating lobes effectively. Simulation results verify the rationality of the proposed principle.
