2009 9th International Conference on Intelligent Transport Systems Telecommunications, (ITST), 2009 In this paper, we present a comparison of two strategies for FMCW radars. The potential presence of multiple targets implies using specific waveforms for beat frequencies association. Here, we compare performance of two such waveforms in terms of targets distance and velocity estimation.

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Seismo‐Acoustic Characterization and Array Processing of Dry‐ and Wet‐Snow Avalanches
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.Abstract Snow avalanches generate complex seismic and infrasound signals influenced by terrain, snow properties, flow regime, and avalanche size. In this controlled field study, we analyzed the seismo‐acoustic characteristics of three avalanches that released along the same path in the Dischma valley above Davos, Switzerland.

On‐Chip Saturated Absorption of CO2 in a Silicon‐on‐Sapphire Waveguide
Advanced Optical Materials, Volume 14, Issue 24, 25 June 2026.We demonstrate the first saturated absorption of a molecular gas on a planar photonic chip. By coupling carbon dioxide with the tightly confined light of a silicon‐on‐sapphire waveguide, we achieve optical saturation using only milliwatt powers. This breakthrough provides a practical, low‐power foundation for creating ultra‐compact mid‐infrared ...

Phase Noise in FMCW Radar Systems [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2019 Phase noise is one of the fundamental performance parameters in modern radar, communication, spectroscopic, and metrological systems. In this paper, a phase noise theory has been developed for FMCW radar systems. A new design equation has been derived to specify the maximum bound on the allowable source phase noise level in radar systems. The nonlinear
