We developed a portable ultra-wideband radar system capable of reconfigurable operation in multiple frequency bands (separate or simultaneous) spanning from microwaves through millimeter waves. The instrument provides a compact solution for fine-resolution measurements of elevation changes and superficial snow/firn thickness from low-altitude, mid-sized airborne platforms. In this article, we provide an overview of the radar system design and its performance during laboratory testing. We demonstrate its application in aerial surveys of snow layer thickness at S/C bands, dual-band airborne altimetry at Ku -/ Ka -bands, and present first-order comparisons with coincident airborne lidar data.

用于雪厚评估和测高的紧凑型、可重新配置的多 UWB 雷达：开发和现场试验


我们开发了一种便携式超宽带雷达系统，能够在从微波到毫米波的多个频段（单独或同时）中进行可重新配置操作。该仪器为低空中型机载平台的高程变化和表面积雪/云杉厚度的精细分辨率测量提供了紧凑的解决方案。在本文中，我们概述了雷达系统设计及其在实验室测试期间的性能。我们展示了其在 S/C 波段雪层厚度航空测量、Ku/Ka 波段双波段机载测高中的应用，并与同步机载激光雷达数据进行一阶比较。
