Micro-Doppler Feature Extraction of Inverse Synthetic Aperture Imaging Laser Radar Using Singular-Spectrum Analysis

Sensors, 2018
Different from microwave radar, laser radar could be more sensitive to the micro-Doppler (m-D) effect due to its wave length. This limits the application of conventional methods, such as time–frequency based approach, since the processing needs a ...

An alternative representation of Synthetic Aperture Radar images as an aid to the interpretation of englacial observations [PDF]

The Cryosphere
Ground-penetrating radar reveals subsurface geometry and ice stratigraphy that contains information about past and present dynamics of the cryosphere. Synthetic Aperture Radar (SAR) is a processing technique based on averaging the radar echoes received ...

A Ground-Based Multi-Doppler Wind Retrieval Algorithm for Turbulent Convection: An LES-Based Radar Wind Retrieval Framework

Remote Sensing
Accurate retrieval of high-resolution three-dimensional (3D) wind fields from Doppler radar observations is essential for understanding the dynamical structure of convective storms and the turbulent processes that govern their evolution.
