Digital FMCW for ultrawideband spectrum sensing [PDF]

open access: yesRadio Science, 2016
AbstractAn ultrawideband digital frequency‐modulated continuous wave sensing engine is proposed as an alternative technique for cognitive radio applications. A dual‐band demonstrator capable of sensing 750 MHz bandwidth in 204.8 µs is presented. Its performance is illustrated from both bench tests and from real‐time measurements of the GSM 900 band and

A FMCW-FSK Combined Waveform for Multi-Target Detection in FMCW Radar

open access: yesDEStech Transactions on Computer Science and Engineering, 2017
Frequency modulated continuous wave (FMCW) radar has been widely applied in many fields. Modulated waveform is usually designed to solve the coupling problem of range and velocity in multi-target situation. A FMCW-FSK combined waveform is proposed in this work, which takes the advantages of FMCW waveform and FSK waveform.

Modeling FMCW Radar for Subsurface Analysis

open access: yesIEEE 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 ...
