摘要：
This paper presents enhanced data products from an airborne ultra-wideband frequency modulated (FM) microwave radar capable of measuring cm-scale of snow cover thickness from high altitude (>1.3 km above ground level, AGL). We use advanced radar hardware combined with a custom synthetic aperture radar (SAR) algorithm applied in post-processing to demonstrate a unique capability of retrieving snow cover depth values down to similar to 5 cm over a <35-m footprint from altitudes as high as 5,800 m AGL. The improved detection capabilities presented here will be advantageous to maximize mapping coverage while maintaining fine granularity during high altitude surveys.
