摘要
GLISTIN (Glacier and Land Ice Surface terrain Interferometer)是一种用于冰原和冰川地形测绘的星载干涉合成孔径雷达。GLISTIN将使用ka波段数字波束形成天线，以次季节重复间隔在一宽带上收集冰地形测量数据。本文将概述系统设计和关键技术演示，包括带有集成数字接收器的Im x Im数字波束形成ka波段波导缝隙天线。我们还将详细介绍我们将用于演示该系统的波束形成和干涉性能的实验场景。
Technology Demonstration of Ka-band Digitally-Beam formed Radar for Ice Topography Mapping
GLISTIN (Glacier and Land Ice Surface Topography Interferometer) is a spaceborne interferometric synthetic aperture radar for topographic mapping of ice sheets and glaciers. GLISTIN will collect ice topography measurements over a wide swath with sub-seasonal repeat intervals using a Ka-Band digitally-beamformed antenna. This paper will give an overview of the system design and key technology demonstrations including a Im x Im digitally-beamformed Ka-band waveguide slot antenna with integrated digital receivers. We will also detail the experimental scenario that we will use to demonstrate both the beamforming and interferometric performance of this system.
