Interpreting How Neural Networks Infer Scatterer Geometry from Echolocation Echoes
Advanced Intelligent Systems, EarlyView.Neural networks enable echolocation‐based shape classification but remain difficult to interpret due to their black‐box nature. This work presents a feature‐importance metric to uncover the echo regions driving decisions in shape‐specialized networks.

An exeriment for high speed retrieval by ENVISAT-ASAR cross-polarized observations
, 2012 We present a new empirical C-band cross-polarization ocean backscatter model for high wind retrievals, from ENVISAT-ASAR. The model relates normalized radar cross section (NRCS) in cross-polarization (VV/VH) to the wind speed at 10-m height.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics
Advanced Physics Research, EarlyView.This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Phong-like Lighting for MMW Radar Simulation
, 2008 Radar simulation involves the computation of a radar response based on the terrain's normalized radar cross section (RCS). In the past different models have been proposed for modeling the normalized RCS.

Archaeological Prospection, EarlyView.ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

, 2014 Previous studies have shown the potentiality of X-band synthetic aperture radar in measuring rainfall. A microwave forward model describes the Normalized Radar Cross Section (NRCS) as composed by a surface contribution and a volumetric contribution and ...

Archaeological Prospection, EarlyView.ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Archaeological Prospection, EarlyView.ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

Measuring the Normalized Radar Cross-Section of the Earth Using Pencil Beam Scatterometers
, 1998 Space-borne scatterometry has been used by NASA for several years to estimate the normalized radar cross-section (σ0) of the surface of the earth. The measured value of σ0 can then be used to study surface features such as vegetation, polar ice and ocean
