Yasin Yavuz, Ertuğrul Aksoy, Mert Karahan
Optimization techniques may be used in time-modulated arrays in order to shape the radiation pattern. Optimized excitation strategies allow the radiation pattern to be steered into desired direction while the side lobe levels are being controlled. In this paper, variable pulse amplitude strategy is used with modifications and differential evolution algorithm is applied to obtain the best results. Using this approach, individual harmonic levels may be enhanced or suppressed in order to be used in different applications. Furthermore, an explanatory example is given in order to visualize the results.
