AI Technical Summary
Existing technologies suffer from high computational complexity, large memory requirements, and poor numerical stability in beam optimization problems in polarized array systems, especially when jointly optimizing horizontal and vertical polarization components.
The beamforming method of polarization time modulation array is used to transform the quadratic constrained quadratic programming optimization problem into an equivalent second-order cone programming problem by utilizing polarization null space theory, and then combining it with genetic algorithm to optimize the phase state to form an ultra-low sidelobe beam.
It significantly reduces optimization complexity, improves numerical stability and efficiency, reduces memory consumption, and the optimization results are more in line with engineering practice.
