Precise Ambiguity Performance Evaluation for Spaceborne SAR with Diverse Waveforms
Remote Sensing, 2023 The ambiguity suppression is a technical challenge for the present generation of spaceborne synthetic aperture radar (SAR) systems since this kind of suppression does not take the high spatial resolution and wide coverage into account simultaneously. The

Advances in InSAR Analysis of Permafrost Terrain
Permafrost and Periglacial Processes, Volume 35, Issue 4, Page 544-556, October/December 2024.ABSTRACT Differential interferometric synthetic aperture radar (InSAR) is a remote sensing technique for measuring surface displacements with precision down to millimeters, most commonly from satellites. In permafrost landscapes, InSAR measurements can provide valuable information on geomorphic processes and hazards, including thaw subsidence and frost

Magnesium Anchoring Strategy for Stabilizing Graphene‐Hosted Lithium Metal Battery
Small Structures, Volume 5, Issue 2, February 2024.A magnesium anchoring strategy is discovered to selectively bond the Mg ion with oxygen functional groups in graphene for preventing the formation of oxygen functional groups‐derived lithium carbonate in solid–electrolyte interphase (SEI), thus building an electrolyte‐derived LiF‐dominated SEI for achieving uniform lithium deposition and stable cycling
