Problems solved by technology

[0004] According to the published optimization design of array antenna sparse distribution, in the process of large-scale array sparse distribution optimization based on genetic algorithm, since the main lobe width of the synthetic beam of large-scale array is extremely narrow, and the main lobe of large-scale array is easy to appear Spikes cause the conventional fitness function to be stuck in local convergence, unable to jump out of the wrong search direction, and the main-to-side ratio optimization fails, which cannot meet the application of large-scale array quantity scenarios

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...

Description

【Technical field】 [0001] The present invention relates to the technical field of array antennas and wireless communication, and in particular, to an antenna array sparse optimization method, device, device and readable storage medium applied in the process of synthesizing low sidelobe beams by large-scale antenna arrays. 【Background technique】 [0002] In radar and communication systems, array antennas are widely used in order to make the antenna have the characteristics of high gain, narrow beam, and low side lobes. Under the premise of a given aperture size, by constraining the distance between the antenna elements and adjusting the position of each array element, the uniformly weighted array can be obtained without significantly changing the corresponding half-power beam width when the array elements are evenly arranged. A non-uniform antenna array (sparse array) composed of elements with reduced side lobe levels. The increased spacing of the array elements can reduce th...
