摘要：
Time modulated linear arrays have attracted the attention of researchers for synthesizing low/ultralow sidelobes in recent past. In this article, CVX convex optimization toolbox and Invasive Weed Optimization are effectively combined to form a hybrid algorithm, the hybrid algorithm is presented to suppress the sideband radiation patterns of time modulated linear arrays. CVX convex optimization toolbox is used to optimize the pulse duration and IWO algorithm is used to optimize the switch-on time variables only. The sidelobe level in center frequency and sideband radiations in harmonic frequencies are all suppressed to desired values. Representative experimental results are presented and compared with existing literature solutions to assess the effectiveness of the proposed approach.
