Robust Pattern Synthesis Algorithm in Time-Modulated Linear Array with Position Errors

The time-modulated array has higher flexibility than the traditional antenna array. However, the time-modulated array is sensitive to random errors. In this paper, the time-modulated uniform linear array with element position errors is discussed. Position errors can not only lower the performance of the array but also lift the side-lobe and increase the dynamic range of the side-lobe. Aimed at this issue, a robust pattern synthesis algorithm is proposed, and simulation results are given to illustrate the effectiveness and the robustness of the proposed algorithm.
