Low Power 24 GHz ad hoc Networking System Based on TDOA for Indoor Localization
ISPRS International Journal of Geo-Information, 2013 This paper introduces the key elements of a novel low-power, high precision localization system based on Time-Difference-of-Arrival (TDOA) distance measurements. The combination of multiple localizable sensor nodes, leads to an ad hoc network.

Modeling FMCW Radar for Subsurface Analysis
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Determining subsurface properties through ground penetrating radar sounding can be challenging, especially in planetary exploration, where little is known about the terrain and additional observations are limited. Analysis and interpretation of data acquired with the Radar Imager for Mars’ Subsurface Experiment (RIMFAX) could therefore be ...

Simultaneous ToF/FMCW LiDAR Using a Dual‐Mode Light Source in a Single Architecture
Laser &Photonics Reviews, EarlyView.A simultaneous ToF/FMCW LiDAR architecture is demonstrated using a dual‐mode light source that alternately generates optical pulses and frequency‐chirped light within a single acquisition. By combining time‐domain ToF and coherent FMCW ranging, the system achieves high‐resolution ranging and velocity sensing while extending the measurable range beyond ...
