摘要：

In this letter, a novel method for synthesizing power pattern in time-modulated linear array is proposed. First, through a study and analysis, it is investigated that both maximum sideband radiation (SRmax) and the total amount of sideband power (P-SR) of the time-modulated array are decreased when the maximum power of the main beam (P-0max) at center frequency is increased toward its maximum value. Then, to synthesize the desired center frequency pattern with suppressed sideband radiations (SRs), unlike the conventional method of dealing SRmax and P-SR other than the desired radiation parameters of the intended pattern, only P-0max is invoked in formulating the cost function. Finally, the computational proficiency and the potential viability of the proposed method to realize the desired pattern by suppressing the SR has been illustrated through representative numerical results.
