Gridless Sparse Recovery-based Wind Speed Estimation for Wind-shear Detection Using Airborne Phased Array Radar [PDF]
RadioengineeringThe accuracy of wind speed estimation is an important factor affecting wind-shear detection in airborne weather radar. Aiming at the problem that dictionary mismatch in the sparse recovery-based wind speed estimation leads to the performance degradation,

Using InSAR Coherence to Map Stand Age in a Boreal Forest
Remote Sensing, 2012 The interferometric coherence parameter γ estimates the degree of correlation between two Synthetic Aperture Radar (SAR) images and can be influenced by vegetation structure. Here, we investigate the use of repeat-pass interferometric coherence &
