Planar antenna array sparse method based on quantum spider population evolution mechanism

Abstract

The invention provides a planar antenna array sparse method based on a quantum spider population evolution mechanism. The planar antenna array sparse method comprises the steps of 1, establishing a planar antenna array sparse model; 2, setting system parameters; 3, performing evaluation on advantages and disadvantages of each spider coding position in a population by a fitness function, and taking the optimal position of the fitness function as the global optimal position of the whole population; 4, dividing genders of spiders in the population; 5, calculating weight of each spider; 6, updating quantum positions of female spiders by adopting an analog quantum vector rotation door rotation based on the updated quantum vector rotary angle; 7, updating quantum positions of male spiders by adopting an analog quantum vector rotation door rotation based on the updated quantum vector rotary angle; 8, updating the respective historical optimal positions; and 9, judging whether the maximum number of iterations is reached or not. By adoption of the planar antenna array sparse method, the difficulty existing in multi-constraint planar array antenna sparsity is solved, and various requirements on the planar sparse array are satisfied.

Description

technical field [0001] The invention relates to a method for constructing an antenna array, in particular to a sparse method for a planar antenna array. Background technique [0002] In recent years, with the advancement of science and technology, the requirements for antenna technology are also increasing, leading to the rapid rise and development of antenna technology. In order to make antennas meet the ever-increasing requirements of rapidly advancing technology, many new types of antennas have emerged, including antenna arrays. The antenna array is to place many antenna elements in a certain arrangement, so that their radiation field vectors are superimposed to obtain a total radiation field to meet the high gain and high directivity requirements in practical applications. The excellent effect shown by the huge antenna array makes the antenna array an indispensable part in some projects. [0003] In some radar and satellite antenna systems, the antenna array is compose...
