Due to the range ambiguity effect and the complex terrain environment, the remote weak target of interest for nonsidelooking airborne radar is usually superimposed with the nonstationary and heterogeneous short-range strong clutter, so it is difficult ...

Feasibility Mapping of L‐Band InSAR for SWE Retrievals Across the Western United States
Abstract Mountain snowpacks provide vital water resources for communities in the western U.S. (WUS), but high spatial variability challenges accurate measurement of snow water equivalent (SWE) from remote sensing platforms. Studies using repeat airborne L‐band (∼25 cm wavelength) Interferometric Synthetic Aperture Radar (InSAR) have demonstrated ...

The SARTOM Project; Tomography for enhanced target detection for foliage penetrating airborne SAR
The SARTOM project addresses a key area of defence interest, namely the detection and identification of targets hidden in foliage. The project has provided a rich source of data obtained from a series of flight trials that were conducted in September ...

Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.

Machine Learning Reveals Hidden Bias in ERA5 Cloud Heights Over Earth's Third Pole
Abstract Accurate cloud base height (CBH) over the Tibetan Plateau—Earth's Third Pole—is essential for monsoon dynamics, glacial melt, and water security, yet ERA5 systematically underestimates it. Here, we present a two‐step machine learning framework to mitigate this hidden bias.

Airborne Dual-Polarized Ku-Band FMCW Synthetic Aperture Radar for Snow Measurements
We developed an ultra-wideband (UWB) dual-polarized Ku-band frequency-modulated continuous-wave (FMCW) airborne radar operating over the 13–18 GHz frequency range for measurements over snow and other targets.
