Performance Evaluation of a Modified SweepSAR Mode for Quad-Pol Application in SAR Systems [PDF]
Journal of Electromagnetic Engineering and Science, 2020 Efficient earth observation using spaceborne synthetic aperture radar (SAR) requires the analysis of high-resolution wide-swath (HRWS) systems, which have a fine resolution and a short revisit time through wide-area observation, and quadrature ...

Methods in Ecology and Evolution, Volume 14, Issue 7, Page 1639-1656, July 2023., 2023 Abstract Vegetation canopy height is a relevant proxy for aboveground biomass, carbon stock, and biodiversity. Wall‐to‐wall information of canopy height with high spatial resolution and accuracy is not yet available on large scales. For the globally consistent TanDEM‐X data, simplifications are necessary to estimate canopy height with semi‐empirical ...

IET Radar, Sonar &Navigation, Volume 16, Issue 10, Page 1696-1716, October 2022., 2022 Abstract The traditional pulse repetition interval (PRI) transform method and modified PRI transform method have a low ability to recognise the complex PRI modulation type adopted in spaceborne synthetic aperture radar systems. To solve this problem, a short‐time modified PRI transform (STMPT) method based on the traditional PRI transform method was ...
