Perturbation Alternating Projections Method for Pattern Synthesis of Phased Array Antenna
Pattern synthesis algorithms for phased array antenna beam shaping are mostly optimization algorithms, and the convergence speed of the algorithms has much influence on their characteristic. Aiming at this problem, this paper proposes an improved perturbation alternating projection method, which is not much affected by optimization algorithm convergence degree constraints. By setting the shaped region of the threshold value, the desired current incentive coefficient and power pattern are iteratively calculated by use of alternating projection method. The coefficients are perturbed constraint in the iterative process, and is made to reach the convergence precision as soon as possible. The simulation results show that the algorithm converges faster and has high precision, which has good application value in practical engineering.
