Digital Canopy Model Estimation from TanDEM-X Interferometry using High-Resolution Lidar DEM [PDF]
, 2013 Interferometric TanDEM-X data are used together with high-resolution, airborne lidar-derived digital elevation models (DEMs) to produce digital canopy models (DCMs) for the boreal forests of Remningstorp and Krycklan, situated in southern and northern ...

Polarimetry for Sparse Multistatic 3D SAR
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.3D SAR imagery provides target height information and removes layover artefacts, but it has impractical sampling requirements. This article develops the PolSSARVI approach, where a sparsely formed set of polarisation‐weighted interferograms are combined for determining the 3D coordinates of scatterers.

Can GNSS reflectometry detect precipitation over oceans? [PDF]
, 2018 For the first time, a rain signature in Global Navigation Satellite System Reflectometry (GNSS‐R) observations is demonstrated. Based on the argument that the forward quasi‐specular scattering relies upon surface gravity waves with lengths larger than ...

High‐Accuracy Frequency Detection and Analysis via Adaptive Frequency Standard Tracking
IET Signal Processing, Volume 2025, Issue 1, 2025.Precise frequency detection is one of the key problems to be solved in a high‐accuracy transfer of time and frequency. The solution to this problem is helpful in improving the precision of the phase noise measurement, atomic frequency standard, and time synchronization, which plays a strong role in the whole precision measurement physics fields. A high‐
