Embodiment 1
[0084] The technical scheme adopted in the present invention is a sparse optimization algorithm based on genetic algorithm or particle swarm algorithm, suitable for synthesizing low sidelobe beams by large-scale antenna array, and its steps are:
[0085] 1) Initialization parameters
[0086] 2) Generate the initial population
[0087] 3) Genetic algorithm loop (calculated according to the maximum genetic algebra loop)
[0088] 3.1 Substitute the fitness function to calculate the maximum sidelobe level
[0089] 3.1.1 In the observation angle sampling of the synthetic array factor, first find the sampling angle with the smallest angle difference from the extreme value of the array factor, and then assign this sampling angle as the angle corresponding to the extreme value of the array factor;
[0090] 3.1.2 Calculate the main lobe width and the number of sampling points of the array composite beam according to the number of array elements and the sampling scale of the observati...
