采用FFT-PSO策略的多约束稀疏阵天线方向图综合
Thinned Array Antenna Pattern Synthesis with Multiple Constraints Using FFT-PSO Strategy
摘要
Abstract
For the thinned array antenna,the peak sidelobe level ( PSLL) of the array with equal amplitude excitation can not meet the requirements of the designed performances. Considering the constraints of an-tenna gain and the half-power beamwidth,the appropriate fitness function is designed,and the excitation amplitude of the element based on particle swarm optimization ( PSO) is optimized to reduce the antenna sidelobe level. Meanwhile,the relationship between the pattern of planar phased array with rectangular grid and the discrete Fourier transform ( DFT) is analyzed,then the fast Fourier transform ( FFT) is used to re-duce the computational complexity. The simulation results show that the proposed approach can effectively reduce the maximum PSLL and the computational complexity.关键词
