The invention provides an annular antenna array sparse method based on a quantum chicken evolution mechanism. The method comprises the following steps that: 1: establishing an annular antenna array sparse model; 2: setting an initial parameter; 3: designing a fitness function; 4: calculating the fitness value of each chick in a population, distinguishing the category of the chicken, and dividing sub-populations; 5, 6, and 7: independently constructing the quantum vector rotation angle update formula of roosters, hens and chicken, updating the quantum vector rotation angle, and updating a quantum position; 8: through a measurement way, converting into a [0,1] coding position, calculating the fitness value of the [0,1] coding position, and updating the individual historical optimal solutionand the global optimal solution of each chick; and 9: judging whether a maximum iteration is achieved or not. The method is higher in rate of convergence and higher in accuracy of convergence, and hasa good spare effect on solving the problem of annular antenna array sparse construction, the complexity and the cost of antenna array system are greatly lowered, and an expectant requirement is achieved.
