“…Both experiments show partial effectiveness of the method as it suffers from increased beamwidth. Further low side lobe level pattern synthesis of uniform linear array has been discussed using BAT algorithm and statistical mean method in the presence of array errors [29]. Then a novel pattern synthesis algorithm for antenna array has been discussed in [30] for eliminating ranges ambiguity in LT-1 mission via sequential convex optimizations.…”

The paper proposes a novel least perturbation based method of constrained null placement for a nonuniformly excited linear antenna array. Synthesis of amplitude and phase of edge element using least perturbation based analytical technique for required null placement leads to degradation of pattern in terms of increased side lobe level and beam broadening. Further computation capability of the method of least perturbation has been enhanced using an evolutionary algorithm. Subsequently, suitable evolutionary algorithms have been employed to find the optimum value of excitation and phase of edge elements subject to constraints of side lobe level reduction, beamwidth narrowing, and main beam control. Design of 8 and 15 elements linear array with a 95% reduction in computation time elucidates the capabilities of the proposed method. Further 3D electromagnetic solver-based validation process has been used to ascertain the practical acceptability of the method.

For the purpose of fulfilling the low sidelobe level (SLL) requirements for spaceborne phased array antenna pattern synthesis, this paper proposes a new improved whale optimization algorithm (IWOA). As a type of new heuristic algorithm inspired by whale hunting behavior, WOA has the advantages of simple structure, few parameters, fast optimization speed, and high precision. In this paper, improvements are made in three aspects of adaptive weight, spiral coefficient optimization, and optimal neighborhood perturbation, and the proposed algorithm is successfully applied to the intelligent calculation of antenna synthesis. In light of the engineering requirements, the mathematical model of the optimization problem is established, and the desired antenna pattern with high gain and low sidelobe is obtained using IWOA under the constraint that the amplitude variation is within 20 dB. Simulation results demonstrate that IWOA is superior in maximum sidelobe level (MSLL) suppression and convergence. Consequently, EM simulations were conducted on a 64-element planar array, with the results consistent with the theoretical simulation, verifying the feasibility and effectiveness of the proposed algorithm.
