FMCW-Radar-Based Electronic Walking Cane for Blind Pedestrians

, 2020
Our new idea of using a simple FMCW radar as an electronic walking cane is described. The letter goes beyond the idea by proposing the required architecture architecture, and even proposed antenna type and usable COTS part numbers.

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

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 ...

A 77/79-GHz Frequency Generator in 16-nm CMOS for FMCW Radar Applications Based on a 26-GHz Oscillator with Co-Generated Third Harmonic

ESSCIRC 2019 - IEEE 45th European Solid State Circuits Conference (ESSCIRC), 2019
This paper presents a digitally controlled frequency generator for dual frequency-band radar system that is optimized for 16 nm FinFET CMOS. It is based on a 21% wide tuning range, fine-resolution DCO with only switchable metal capacitors. A third-harmonic boosting DCO simultaneously generates 22.5–28 GHz and sufficiently strong 68–84 GHz signals to ...

ADCC‐TFNet: Adaptive Dynamic Complex Convolution for Radar Micro‐Doppler Time‐Frequency Representation of Low‐Slow‐Small Targets

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper addresses the problem of time‐frequency representation (TFR) for radar micro‐Doppler signals of low‐slow‐small (LSS) targets under noisy and multi‐component conditions. ADCC‐TFNet is proposed to generate input‐conditioned complex kernels and enhance time‐frequency ridge continuity and concentration.
