Pol-Insar Forest Height Inversion Using Tomosar Reflectivity Profiles [PDF]

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The realistic parameterization of the underlying (vertical) radar reflectivity profile is critical for a model-based inversion of forest height from polarimetric interferometric (Pol-InSAR) data. Indeed, an appropriate parameterization not only affects the final estimation performance, but also enables the inversion from a reduced observation space in ...

UAVSAR Tomography for Vertical Profile Generation of Tropical Forest of Mondah National Park, Gabon

Earth and Space Science, Volume 7, Issue 10, October 2020., 2020
Abstract Polarimetric synthetic‐aperture radar (SAR) remote sensing has been widely used for structural and biophysical parameters retrieval of forest vegetation. It has been found that the combination of polarimetric properties and interferometric characteristics of SAR remote sensing provides the capacity to retrieve forest height.

Elevation Extraction from Spaceborne SAR Tomography Using Multi-Baseline COSMO-SkyMed SAR Data

Remote Sensing, 2022
SAR tomography (TomoSAR) extends SAR interferometry (InSAR) to image a complex 3D scene with multiple scatterers within the same SAR cell. The phase calibration method and the super-resolution reconstruction method play a crucial role in 3D TomoSAR ...

Remote Monitoring of Civil Infrastructure Based on TomoSAR

Infrastructures, 2022
Structural health monitoring and damage detection tools are extremely important topics nowadays with the civil infrastructure aging and deteriorating problems observed in urban areas. These tasks can be done by visual inspection and by using traditional in situ methods, such as leveling or using traditional mechanical and electrical sensors, but these ...
