摘要

本文介绍了一种用于雪崩雷达地球物理成像的5.3 GHz相控阵天线的设计与分析。该天线采用重叠子阵列设计，在±15°视场范围内工作，同时具有抑制光栅瓣的图案。结果表明，在获得390 MHz宽频带和14.5 dBi增益的同时，实现了理想的波束宽度和辐射方向图。

Phased-array antenna feed network for geophysical FMCW radar

This paper presents the design and analysis of a 5.3 GHz phased array antenna for radar geophysical imaging of snow avalanches. The antenna is designed by utilizing overlapping sub-arrays to operate over a ±15° field of view while having a pattern which suppresses the grating lobes. The presented results indicate that the desired beamwidth and radiation pattern are achieved while an ample bandwidth of 390 MHz and a gain of 14.5 dBi are reached.
