Abstract
For the rectangular planar thinned array with the design constraint of the filling factor,a differen-tial evolution algorithm based on integer code is proposed to reduce the peak sidelobe level( PSLL) . In or-der to avoid the infeasible solution during the optimization,the position number of grid is set as the optimi-zation variable on the premise of the condition that the thinned ratio constraint is satisfied and the variables are reduced. Meanwhile,a fast Fourier transform( FFT) is employed to speed up the calculation of pattern. Then the proposed method is applied to design a low side lobe rectangular planar thinned array. The simu-lated results show that the PSLL is reduced by 1 . 2~1 . 7 dB and good convergence and stability can be a-chieved.关键词
