Target Superresolution Reconstruction Approach for Bistatic Airborne Radar Based on Joint Convolution Echo Model

Remote Sensing
Bistatic airborne radar is widely studied because of its separated geometric configuration, offering flexible imaging ability for its receiver. However, when the bistatic platforms work in a synthetic aperture radar (SAR) mode, the bistatic system should

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...
