基于2种不同单元形式的相控阵天线设计比较

Comparison of phased array antenna design based on two different unit forms

对相控阵天线的二维相扫、波束控制、栅瓣、波束展宽等关键点进行了讨论,并结合某型产品设计了2组阵面。通过仿真计算和实物实测,对开口波导单元和印刷振子单元以及2种不同单元各自组阵的情况加以比较,阐明两者之间的优缺点及在不同领域的应用,为后续工程应用提供了参考和支撑。

The key points of AESA such as two-dimensional phase scanning,beam-steering,grating-lobe,and beam-broadening are discussed,and two sets of array surfaces based on a certain project are designed.Through simulation calculations and physical measurements,a comparison is made between the open waveguide and printing-oscillator,as well as their respective arrays,to elucidate the advantages and disadvantages of the two and their applications in different fields.Reference and support for subsequent engineering applications is provided.
