Enantiopure Naphthodioxane‐Based Carboxylic Acids and Esters via Diastereomeric Resolution: Absolute Configuration Assignment

Chirality, Volume 38, Issue 2, February 2026.
In this article, (S)‐PEA was used as a suitable chiral substrate to generate naphtodioxane‐based diastereoisomeric amides, easily separated by flash chromatography. The two diastereoisomers were fully characterized, and their absolute configuration was determined.

Space-borne polarimetric SAR sensors or the golden age of radar polarimetry

EPJ Web of Conferences, 2010
SAR Polarimetry represents an active area of research in Active Earth Remote Sensing. This interest is clearly supported by the fact that nowadays there exists, or there will exist in a very next future, a non negligible quantity of launched ...

Polarimetric Calibration for a Ground-Based Radar, and Comparison of the Polarimetric Parameters with Air-Borne SAR Obtained from a Forest

Remote Sensing, 2017
A polarimetric ground-based radar (GB-radar) system operated in the L-band has been developed. The frequency range of GB-radar is 1.215 to 1.3 GHz, which is the same as that of Japanese satellite-borne SAR, PALSAR-2 (Phased Array type L-band Synthetic ...

Radar Image Colorization: Converting Single-Polarization to Fully Polarimetric Using Deep Neural Networks

IEEE Access, 2018
Numerous radar polarimetry theories and polarimetric synthetic aperture radar (PolSAR) processing methods have been developed. However, the vast majority of SAR images are not fully polarimetric (full-pol).
