An Anti-Interference Antenna Array Sparsity Method Based on White Crane Swarm Algorithm

Sparse antenna array is designed to address the high cost and complexity of array antenna devices. Null steering technique is proposed to suppress the interference that electromagnetic environment exists widely. So as to find an antenna array sparsity method that can reduce the antenna cost and suppress interference while keeping the sidelobe level of the array low, the antenna array sparsity problem and the formation of null steering are designed as a constrained optimization problem, which the traditional optimization algorithms cannot be directly used to solve. Thus, the white crane swarm algorithm (WCSA) is designed and obtains better optimization effects than some traditional optimization algorithms. Additionally, WCSA gets better optimization results for antenna array sparsity constrained optimization problems than some traditional optimization algorithms.
