摘要

分析了阵列天线波束形成的不同功率分配方法。在本研究中，考虑均匀半波长元件间间距以避免光栅瓣。单个元素的激励包括高斯、泰勒、切比雪夫和阶梯功率分布(SPD)。设计要求包括波束效率(BE)、最大旁瓣电平(MSLL)和3db波束宽度。为了充分实现设计目标，对这些方法进行了比较研究。

Comparative study of different power distribution methods for array antenna beamforming for soil moisture radiometer

Different power distribution methods of array antenna beamforming are analyzed. In this study, uniform half-wavelength inter-element spacing is considered to avoid grating lobe. Excitations to individual elements include Gaussian, Taylor's, Chebyshev's and Staircase Power Distribution (SPD). Design requirements include beam efficiency (BE), maximum sidelobe level (MSLL) and 3 dB beamwidth. A comparative study of these methods is carried out to full-fill the design goal.
